How to Link a Discussion Group to a Telegram Channel

To link a discussion group, open your channel's settings, find the Discussion option, and either pick a group you already admin or create a new one. Once linked, every new channel post is copied into the group automatically, and readers get a comments button under each post. Their comments live in the group, so the group's settings and moderators decide what is allowed.

This guide explains how the link works, how to set it up on each platform, which group settings to change straight away, and how to keep comments useful rather than full of spam.

How a linked discussion group works

A channel and a group are different tools. A channel is one-way: admins post, subscribers read. A group is a conversation: members talk to each other. Linking the two gives you a broadcast with a conversation attached.

Behind the scenes, three things happen when you link a group:

1. Each new channel post is forwarded into the group automatically. It appears in the group's chat as a message from the channel.
2. The channel post gets a comments button. Readers tap it to open a thread made of replies to that forwarded copy.
3. Comments are messages in the group. Every comment is a reply inside the group. Anyone who opens the group itself sees the channel posts and all the replies mixed together in one chat.

That last point is the one people miss. A linked group is not a hidden comment box. It is a full group, and comments are just one way into it.

The pairing rules

• A channel can have one discussion group at a time.
• A group can serve as the discussion group for one channel at a time.
• The group is converted to the kind of group Telegram needs for this, if it is not already, and that change is not reversed if you unlink later.
• You need to be an admin of both the channel and the group, with enough rights in each, to link them.

Telegram calls very large modern groups supergroups. Groups can hold up to 200,000 members, which is plenty for almost any comment section.

Why link a group at all

What you gain

• Feedback on each post. Readers can ask questions, add information or point out errors where they belong: under the post.
• A community space. Readers who comment start talking to each other. Over time, a channel's audience can become a community. The strategy side is covered in how to turn a Telegram channel into a community.
• Signals about what works. Posts that attract real discussion tell you what your audience cares about, beyond views and reactions.
• Support in one place. Shops and services can answer common questions publicly, so the next reader finds the answer already there.

What it costs

• Moderation time. Every open comment section attracts spam, scams and arguments. Someone has to watch it.
• Exposure for members. Commenters are visible to everyone who opens the thread. Some readers will never comment for that reason, and that is fine.
• Noise in the group. If the group already has its own conversation, channel posts appear in the middle of it.

If you cannot commit to moderating, reactions may be enough. They give readers a way to respond without any text to moderate.

Before you start

Make these decisions first. Changing them later is possible but messier.

1. New group or existing group? A new group starts clean and exists only for comments. An existing group brings its members and history, and channel posts will start appearing in its chat.
2. Public or private group? A public group has its own username and can be found in search. A private one is reachable only by invite link or through the comments button. Either works for comments.
3. Who will moderate? Pick at least one person besides you. Comment sections tend to get busy at the worst times, such as late at night after a popular post.
4. What are the rules? Write them before the first comment arrives. A ready-made set is in the Telegram group rules template.
5. Which app? Any official Telegram app can do this. Mobile and desktop apps show the options most reliably; update yours first.

How to link a discussion group, step by step

Menu wording changes between Telegram versions. The option is usually labelled "Discussion" and sits in the channel's edit or management screen. If your screen looks different, look for that word.

Create a new group from the channel (Android and iPhone)

1. Open your channel and tap its name at the top.
2. Tap the edit option (a pencil icon on Android, "Edit" on iPhone).
3. Tap "Discussion".
4. Choose the option to create a new group.
5. Give the group a name. Many owners use the channel's name plus "Chat" or "Comments", so readers can tell they belong together.
6. Confirm. Telegram creates the group and links it in one step.
7. Go back to the channel and publish a test post. A comments button should appear under it.

Link a group you already have (Android and iPhone)

1. Make sure you are an admin of the group with rights to change its info.
2. Open the channel, tap its name, then the edit option.
3. Tap "Discussion".
4. Choose the group from the list. Only groups where you have enough admin rights appear.
5. Read the confirmation. Telegram explains that new posts will be forwarded into the group.
6. Confirm the link.

On Telegram Desktop

1. Open the channel and open its management or edit screen from the menu at the top right.
2. Find "Discussion".
3. Choose to create a new group or select an existing one.
4. Confirm.

On Telegram Web

The web apps follow the same pattern through the channel's info and edit screens. If the Discussion option is missing in your browser version, use a phone or desktop app; the link works everywhere once it exists.

Check that it worked

• New posts show a comments button or a "Leave a comment" link.
• Opening the group shows the new post forwarded into it from the channel.
• A test comment from a second account appears both in the thread and in the group.

If the comments button is missing, jump to the troubleshooting section below or to Telegram channel comments not showing.

The settings to change right after linking

Linking switches on comments with the group's existing permissions. Those defaults are usually too open for a public channel. Spend ten minutes on the group's settings before your next post.

Decide whether commenters must join

For linked groups, Telegram offers a choice between letting readers comment straight from the post and requiring them to join the group before they can write. The option appears in the group's settings or permissions in recent versions.

• Letting anyone comment gets more comments, including from people who would never join.
• Requiring them to join filters out some drive-by spam and gives you a clearer member list to moderate.

There is no right answer. News channels with large audiences often require joining; small expert channels often leave it open.

Consider approving new members

A group can require admins to approve each person who asks to join. On a busy channel this is a lot of work, but it stops waves of spam accounts. It also works well when combined with joining being required for comments.

Set member permissions

In the group's permissions, decide what ordinary members may send. Common choices for comment sections:

• Allow text, and perhaps photos.
• Restrict links, or allow them only for trusted members, because links are the main tool of scammers.
• Restrict stickers and GIFs if threads become walls of images.
• Turn off adding members, which a comment section never needs.
• Turn off pinning and changing group info for members.

Use slow mode during busy periods

Slow mode limits how often each member can send a message. It cools down heated threads and slows spam bots. Turn it on for controversial posts and off again afterwards. Details are in slow mode and member restrictions.

Add anti-spam help

Telegram has built-in tools for larger groups, and admins often add a moderation bot as well. Give any bot only the rights it needs. How to stop spam bots in Telegram groups covers the options.

Pin the rules

Pin a short rules message in the group so anyone who opens it sees them. Readers who comment from the channel may never see the pin, so keep the most important rule visible in your behaviour too: remove rule-breaking comments quickly and consistently.

What readers and members see

Understanding the reader's view helps you design the setup.

A subscriber who never opens the group

They see channel posts as usual, with a comments count and button. Tapping it opens a thread of replies for that one post. Depending on your settings, they can reply without joining, or they are prompted to join first.

A member of the group

They see the group chat, where every channel post arrives as a forwarded message, and comments appear as replies. If your channel posts often, the group becomes a mix of posts and conversations. Some members love this; others mute the group and only use the comment threads.

Who can see whom

Commenters appear with their name and profile photo, like any group member. If your readers are sensitive about privacy, tell them this before they comment. In a channel, subscribers are invisible to each other. In a comment thread, they are not.

Commenting as a channel

Telegram lets people send messages in some groups as one of their own channels instead of as themselves. In a comment section, that means you may see comments posted under another channel's name. This is often used for promotion. If it becomes a problem, restrict or remove those comments the same way you would any spam, and check the group settings for any option Telegram offers to limit it.

Public or private group: the details that matter

The choice you made before linking has knock-on effects. Here is what each option changes in practice.

A public discussion group

• It can be found in Telegram's search by its name or username, so people can join without ever seeing your channel. That can be a growth path, and it is also how spammers find you.
• Its username is one more thing to protect. If you later make the group private, the username is freed and someone else could take it.
• Anyone can preview it before joining, which helps readers decide whether the conversation is worth their time.

A private discussion group

• It is reachable only through the comments button or an invite link. That keeps the conversation tied to your channel's readers.
• Invite links can be controlled. You can create separate links, limit them, or revoke them if one leaks onto a spam list.
• Spam is usually lower, though not absent, since bots that read channel posts can still reach the comments.

Chat history for new members

Groups have a setting for whether new members can see messages sent before they joined. For a discussion group, keeping the history visible is usually right: a new reader who joins wants to see past threads. Hiding it can make sense for a private group where earlier conversations were more personal. Check the group's settings for this option and choose deliberately rather than leaving the default.

Moderating comments day to day

The basic tools

From any comment, an admin can:

• delete the comment
• delete all recent messages from that person
• restrict the person, for example to read-only
• ban the person from the group
• report the comment to Telegram

Restricting is often better than banning for a first offence, because it keeps the person reading without letting them post. For a full approach to bigger groups, see how to moderate a large Telegram group.

A simple moderation routine

1. Check new posts' threads in the first hour. That is when most comments and most spam arrive.
2. Remove scams immediately. Fake giveaways, "contact me for investment" replies and impersonators of your admins are the most common. Ban rather than restrict.
3. Answer real questions. A comment section where questions get answered attracts better comments.
4. Note repeat problems. If the same kind of spam keeps arriving, change a permission rather than deleting it forever by hand.
5. Agree on escalation. Decide in advance who handles threats, harassment or legal issues, and how to report them to Telegram.

Impersonation of admins

A common scam in comment sections is an account using your channel's name and photo, replying to readers with "contact me for a prize" or "I can help you recover funds". Warn readers in your rules that admins never DM first about money. Ban these accounts on sight, and report them.

Getting better comments, not just more

A comment section reflects how you use it. A few habits change the tone more than any setting.

Ask something specific

"What do you think?" gets little. A post that ends with a concrete question, such as which of two options readers would choose or what they would add to a list, gives people an easy way in. Keep it genuine; readers notice when questions are only there to farm replies.

Reply as the channel

Admins can usually post in the linked group as the channel itself rather than under their personal names. Answers from the channel's name read as official, which suits announcements and corrections. Personal replies suit friendly chat. Pick one style for each kind of reply so readers know what an admin answer looks like, and so impersonators stand out.

Turn good comments into posts

When a reader adds a useful correction or tip, credit them in a follow-up post. Other readers learn that thoughtful comments are noticed. This is one of the cheapest ways to grow a culture of useful replies.

Close the loop on questions

If many readers ask the same thing under a post, answer once in the thread and then edit the original post or publish a short update. Repeated questions are a sign the post left something out.

Watch what the threads tell you

You do not need special tools for this. Once a week, look at which posts drew the most real discussion and which drew only spam or arguments. Posts that start useful conversations are worth repeating. Channel statistics can help with the wider picture.

Turning comments off for a single post

You may want comments on most posts but not on a particular one, such as an announcement about a sensitive event. Telegram's options for doing this have changed over time and vary by app. Some admins delete the forwarded copy of that post from the group, which removes its thread. Check your app for a per-post option before doing that, and test on a quiet post first so you know exactly what happens to the channel post's comments button.

Unlinking or switching the group

How to unlink

1. Open the channel's edit screen.
2. Tap "Discussion".
3. Choose the option to unlink or remove the group.
4. Confirm.

After unlinking, new posts no longer get a comments button and are no longer forwarded into the group. The group itself is not deleted. Its existing messages, including old forwarded posts and their replies, stay in the group.

How to switch to a different group

Unlink the current group, then link the new one using the steps above. Members of the old group are not moved. If you want them in the new group, post an invite link in both places for a while. Separate, revocable invite links make it easy to see which route people use.

Why switch at all?

• The old group has a history or reputation you want to leave behind.
• The old group's spam problem got out of hand and a fresh start with stricter settings is simpler.
• You want to separate a busy community chat from a cleaner comments-only group.

A rollout plan for an established channel

Adding comments to a channel that already has a large, quiet audience changes how it feels. A short plan avoids a messy first week.

1. Set up the group a few days early. Link it, configure permissions, add moderators and pin the rules while nobody is watching.
2. Test with a small, low-stakes post. Check that the comments button appears, that permissions behave as expected and that your anti-spam bot reacts correctly.
3. Announce the change. Tell subscribers that comments are now open, what they are for and what the main rules are. Readers who dislike comments can simply ignore the button.
4. Be present for the first few posts. Answer early comments yourself. The first threads set the tone that later commenters copy.
5. Review after two weeks. Look at what went wrong, then tighten or relax permissions. It is easier to loosen strict settings than to clean up after loose ones.

If the experiment fails, unlink the group. Your channel returns to how it was, and the group keeps its history in case you try again.

Troubleshooting

The group I want does not appear in the list

How to recognise it: you open Discussion, but your group is missing.

1. Check that you are an admin of the group, not just a member.
2. Check that your admin rights include changing the group's info. Ask the owner if not.
3. Check whether the group is already linked to another channel. A group can serve only one.
4. Update your app and try again, or try from another device.

If that does not work: create a new group from the Discussion screen instead, and invite the old group's members to it.

Old posts have no comments button

How to recognise it: posts published after linking have comments; older ones do not.

This is how linking works. Comments attach to posts forwarded into the group, and older posts were never forwarded. There is no button to add comments to the past. If an old post deserves discussion, publish a short new post that links to it.

Readers say they cannot comment

How to recognise it: the button is there, but some readers cannot write.

Work through the likely causes:

1. They must join first. If joining is required, they need to join the group. If joining needs approval, someone must approve them.
2. Permissions block them. Check the group's member permissions. If text messages are off, nobody can comment.
3. They are restricted or banned. Check the group's lists of removed and restricted users.
4. Slow mode is on. They may have to wait before their next comment.
5. Their own settings. Rarely, an account limited by Telegram for spam cannot send messages to strangers' groups.

If that does not work: ask the reader exactly what message they see when they try to send, since Telegram usually names the restriction.

Comments disappeared

How to recognise it: a thread that had comments now shows none.

1. Check whether someone deleted the forwarded copy of that post in the group. That removes its thread.
2. Check the group's recent admin actions for deletions.
3. Check whether the group was unlinked or replaced.

Spam floods every new post

How to recognise it: within seconds of each post, bot replies appear.

1. Require joining before commenting.
2. Turn on approval of new members for a while.
3. Restrict links and media for new members.
4. Add a trusted anti-spam bot with minimal rights.
5. Use slow mode on the busiest posts.

If that does not work: consider a fresh group with stricter settings from the start, and unlink the old one.

Common mistakes

• Linking a busy community group without warning. Members suddenly see every channel post in their chat and leave.
• Leaving default permissions. Open links and media turn the first viral post into a spam magnet.
• No second moderator. One admin cannot watch every thread.
• Expecting comments on old posts. Only posts published after linking get threads.
• Deleting the group to "turn off comments". Unlink instead. Deleting loses every conversation.
• Ignoring impersonators. Fake admin accounts in comments are one of the most common ways readers get scammed.
• Not writing rules. Moderation without published rules feels arbitrary to members and leads to arguments.

Three realistic setups

A news channel (example)

A city news channel links a new public group named after the channel. Commenters must join, links are blocked for members, and slow mode is turned on for posts about elections. Two volunteer moderators cover evenings. The group's pinned message lists five rules and says admins never DM first.

A small expert channel (example)

A channel about home espresso links a private group created for comments. Joining is not required, so readers comment straight from posts. Spam is rare because the audience is small. The owner answers questions in the threads, and the best answers become new posts.

An online shop (example)

A shop links its existing customer chat. Before linking, it announces the change and explains that product posts will now appear in the chat. Members can ask about each product under its post, and staff answer within the day. Links are restricted to admins so scammers cannot post fake payment pages.

What to do next

• Write and pin your rules before the first busy post.
• Set up a short welcome message for new members that points to the rules.
• When your channel has an active, well-moderated community, list it on TGDirectory. Listing is free and every submission is reviewed by a person.

FAQ

Can I link more than one group to a channel?

No. A channel has one discussion group at a time, and a group can serve one channel at a time. If you need several conversations, consider a group with topics, linked separately through invite links.

Do I need a new group, or can I use my existing one?

Either works. A new group stays focused on comments. An existing group brings its members, but every new channel post will start appearing in its chat.

Will my channel's subscribers automatically join the group?

No. Subscribers can comment on posts, and depending on your settings they may be asked to join first. Joining the channel does not add anyone to the group.

Can readers see who commented?

Yes. Commenters appear with their names and profile photos, like any group member. Subscribers of a channel are hidden from each other, but commenters are not.

What happens to comments if I unlink the group?

They stay in the group as ordinary messages and replies. New posts simply stop being forwarded and stop showing a comments button.

Is a linked group the same as enabling comments?

Yes, in practice. Telegram channel comments are powered by a linked group. The step-by-step version focused only on the button is in how to enable comments on a Telegram channel.

Summary

Linking a discussion group is how Telegram adds comments to a channel. Pick or create a group from the Discussion option in the channel's settings, and every new post is forwarded into it with a comments thread attached. Before readers arrive, set the group's join rules, permissions, slow mode and anti-spam help, and agree who moderates. Expect comments only on posts published after linking, unlink rather than delete when you want to stop, and act quickly on spam and impersonators so the comments stay worth reading.
