Comments
Comments let you discuss a Task with your team without changing the Task itself. You will find them in the activity section of the single Task view, where they appear in the same timeline as the Task’s history.
Writing a comment
Add a comment to any Task to talk it over with the other members of the List. Comments use the same Markdown editor as Task descriptions, so you can format your message with headings, lists, links, and code. What you write is safely rendered, so formatting is applied without letting comments run scripts or unsafe markup.
Once posted, a comment joins the Task’s activity stream. You can filter that stream by comments to follow the conversation on its own, or read it together with the change history.
Mentioning another Task
Every Task has a number shown in its row and detail, like #123. Type that number in a comment to highlight it and link straight to that Task, so you can point teammates to related work without leaving the conversation.
Where Comments are available
Where Comments can be used is set by your site’s administrator. By default they are available in Cowork Lists, where discussing a shared Task with your team is most useful. An administrator can also make them available in Private, in both, or turn them off. If you do not see the comment control, it has not been enabled for that List.
