Forum topics or separate groups for a growing community

Every community admin hits the same wall eventually. The group that started as one friendly chat now has three different conversations happening at once, half the members are muted because the noise got unbearable, and pinned messages are buried under a hundred new ones by lunchtime. At that point you’ve got two real options on Telegram: turn on forum topics inside the group you already have, or split the community into separate groups. Both solve the noise problem. They solve it in genuinely different ways, and picking the wrong one costs you admin time later.

What forum topics actually are

Forum topics are a setting on a supergroup, not a separate feature or a separate chat type. An admin with the right to manage the group opens group settings, enables “Topics,” and the group becomes a forum. Everything that existed before turns into the “General” topic, and from then on, admins (or anyone the admin has given topic-creation rights to) can spin up new topics, each with its own name and icon, inside that same group.

The important part is that it’s still one group. One member list, one set of admins, one invite link, one place where the group’s permissions live. What changes is that messages get sorted into threads. A member can look at the topic list and only open the ones they care about, mute a single topic instead of the whole group, and pin a message per topic instead of fighting over one pinned slot for the entire community.

Moderation doesn’t follow the same split. Banning, muting, slow mode, and admin permissions are still group-wide settings. If you ban someone from a topic conversation, you’ve banned them from the group, full stop. There’s no such thing as a topic-level ban. If your bots post into the group, they need to be topic-aware to land messages in the right thread (the Bot API added a thread parameter for exactly this), so any bot you’re already running for welcome messages, rules, or logging needs to be checked or it’ll dump everything into General regardless of where it’s supposed to go.

What separate groups actually are

A second group is a genuinely separate object. Its own member list, its own invite link, its own admin team if you want one, its own permission settings, its own history that a member outside the group can’t see at all. Nothing about it is derived from the first group. If someone is banned from group A, they can still be a full member of group B unless you ban them there too.

This is the part people underestimate: every group you create is another surface to secure and maintain. Another invite link that can leak or get scraped and posted somewhere it shouldn’t be. Another set of admins to appoint and keep honest. Another place spam bots will eventually find and probe. If you’re running the group through an MTProto proxy setup for your community (which is a fair chunk of what we do at telegramvault.org), the proxy layer itself doesn’t care how many groups you run through it, it’s just a transport. But every additional group is still an additional thing a human has to watch, moderate, and keep an invite link alive for.

Where topics fall apart

Topics assume the audience is basically one audience that just wants better organization. That assumption breaks in a few specific ways.

If different segments of your community genuinely shouldn’t see each other’s content at all, topics don’t give you that. Anyone in the group can see the full topic list by default, even ones they haven’t opened. You can restrict who can create topics, but you can’t wall off a topic so only a subset of members even know it exists, the way you can with a genuinely separate group that people have to be individually invited into.

If you want different admin teams running different parts of the community with different authority, topics are also the wrong tool. Admin rights in a forum are still group-wide. You can’t make someone an admin of just one topic. The moment you need “this person moderates the trading topic but has zero authority anywhere else,” you’re describing a separate group with its own admin list, not a topic.

And topics don’t help if the real problem is that your group has outgrown a single invite link. If you’re managing access carefully, rotating links, tracking which link brought in which wave of members, a single forum group still only has the invite-link controls a single group has. Splitting by topic doesn’t multiply your invite-link options.

Where separate groups fall apart

Separate groups solve the isolation and admin-authority problems, but they create their own overhead, and it’s worth being honest about what that overhead actually is.

Each new group is a new set of settings to configure correctly on day one: permissions, slow mode, admin rights, join approval if you use it. Get one of those wrong and it’s not a shared setting you fix once, it’s a mistake you now have to fix in every group separately.

Search and history also don’t cross group boundaries. A member trying to find an old message has to know which group it was posted in. Inside a forum, at least everything is searchable within the one group regardless of which topic it landed in.

There’s also an account-level cost that’s easy to miss if you’re an admin running several communities off a small number of accounts, which is common if you’re managing this professionally rather than as a single hobby group. Telegram accounts have a cap on how many groups and channels they can be a member of. Every extra group you spin up for one community eats into that same shared limit across everything else you administer. If you’re already running multiple communities from a handful of admin accounts, adding five topic-equivalent groups per community adds up fast and can push an account toward that ceiling. A forum with fifteen topics costs that account exactly one membership slot. Fifteen separate groups costs fifteen.

Deciding without overthinking it

The honest litmus test isn’t “how much traffic do we have,” it’s “does any part of this audience need to be kept apart from another part, or does it need a separate admin authority.” If the answer to both is no, and what you actually have is one audience that just wants quieter, better-organized conversation, forum topics are the right call and the lower-maintenance one. You keep one invite link, one member list, one place to apply group-wide rules, and you get threaded conversations without spinning up new infrastructure.

If the answer to either is yes, whether that’s a paid tier that non-paying members shouldn’t see, a regional team with its own moderators, or content that genuinely needs to be invite-only within an invite-only community, a separate group is doing something topics structurally cannot. In that case, plan for the overhead honestly: a real invite-link strategy, a real admin list per group, and a real habit of checking each group individually instead of assuming settings from your main group carried over.

A lot of admins end up running both at once, and that’s not indecision, it’s usually correct. The general community lives in one forum with topics for its different discussion threads, and anything that needs genuine separation, whether that’s a paid group, a staff-only space, or a regional chapter, gets its own group entirely. Just go into that setup knowing which problem each piece is actually solving, so you’re not trying to fix an admin-authority problem by creating another topic, or trying to fix a noise problem by standing up a group you now have to secure and moderate forever.
