A pinned message is a post or announcement that a moderator or admin fixes to the top of a channel or community space, so it stays visible no matter how much new activity happens below it. It's used for information the group needs to see regardless of when they joined the conversation.

‍

‍Why it matters

Active communities move fast, and a regular message gets buried within minutes once conversation picks up. Pinning solves this specifically for information that has to stay visible long after it was posted, rules, a roadmap update, frequently asked questions, rather than relying on members to scroll back and find it.

‍

‍What good pinned content looks like

The most effective pinned messages are kept short and updated rather than stacked, since a channel with ten accumulated pinned messages defeats the purpose just as much as having none. Communities that manage this well review pinned content on a schedule and unpin anything that's gone stale, like an announcement for an event that already happened, rather than letting outdated pins pile up indefinitely.
