Comments, files and checklists
Talk about the work on the task, attach files, tick off steps and post project updates.
Comments
Write in the task panel's Comments tab. Type @ to mention someone - they are told in the bell (and by email if they want). Attach files to a comment with the clip. Press Ctrl + Enter to send.
You can edit your own comments; a project manager can delete any comment.
Project updates
On a project's Activity tab, post an update for the whole team: what's done, what's next, what's blocked. The activity feed also shows everything that happened in the project, day by day.
Files
Attach files to a task (Attach) or to a comment. Documents for the whole project go in its Documents tab - see Documents. Files up to 25 MB each; your plan sets the total storage.
When the project has clients, tick Team only under a comment to keep it from them.
Checklists
A checklist is a list of small steps inside a task. Paste several lines at once to add many. Drag to reorder; double-click an item to change it.
