You can edit or delete your own comment at any time after posting it. There is no time limit and no window that closes: a comment from last year can still be edited today. Open the three-dot menu at the top right of your comment and choose Edit or Delete. Deleting asks you to confirm first.
This works the same way on projects, journals, publications, competitions and topics.
Only the person who wrote a comment can change it
The menu offers Edit and Delete on your own comments and Report on everyone else's. That holds even on your own page: owning the project, journal or publication does not let you edit or remove what somebody else wrote on it. Report is the route for a comment that should not stand.
What an edit does, and what it does not
- The new text replaces the old. Nothing keeps a copy of what was there before, so an edit cannot be undone.
- A comment is capped at 3,000 characters, and the edited version is held to the same cap.
- Links pointing off UNI are not shown. An address outside uni.xyz is hidden when the comment is displayed rather than removed when it is saved, so treat anything you paste into a comment as kept. Links to uni.xyz pages are shown normally.
- An edit is not announced. Do not count on anyone noticing that a comment changed after they replied to it.
- A name you add while editing is not notified. Typing @someone into an edit shows their name as a link but does not tell them. To reach a person, post a new comment mentioning them rather than editing an old one.
What deleting does to the replies underneath
Deleting is not reversible, and it is a withdrawal rather than an erasure. Your comment stops being shown and its text is put out of reach, but the thread hanging off it stays where it is.
- A comment with no replies disappears from the thread.
- A comment with replies stays in place as
[deleted], with your name removed, and the replies remain readable underneath it.
There is no way to take the replies down with it. Each reply belongs to the person who wrote it, and only they can delete it. If a reply needs to come down, report it.
