Lock comments

How to get there: Click All Posts in the sidebar, open a post, click the More (⋯) menu, then choose Lock Comments.

Locking a post closes its comment thread to your end users without hiding any of the existing discussion. The conversation stays visible and searchable, but no new public comments can be added.

What changes when a post is locked

  • Existing comments remain in place. Votes, replies, and pinned comments are untouched.
  • The comment composer is replaced with a "Comments are closed" message for non-admin users.
  • Admins still see a working comment box. A small "Admins can still add comments" note appears below it, so you can post a wrap-up reply or moderator note even after locking.
  • Internal comments are unaffected. Your team can keep dropping internal notes regardless of the lock state.
  • The lock applies to one post at a time. Use the same More menu to unlock (the option flips to Unlock Comments).

When to lock a post

  • Released features. The post has shipped, the changelog entry exists, and you do not want late "+1" comments piling up.
  • Hot or off-topic threads. A discussion has drifted into arguments, repeats, or moderation work that outweighs its value.
  • Archived or won't-do posts. You have explained the decision and want the thread frozen as the canonical answer.
  • Duplicates before merging. Lock the duplicate so users add to the canonical post instead. See merging posts.

Board-level setting

A board (tab) can also be configured to block comments on every post it contains. If the board has comments disabled, every post inside it behaves as locked for end users, regardless of the per-post toggle. You can change this per board in Settings, Boards, on the board's settings.
