Within Teamwork, you can comment on project items such as tasks, milestones, files, notebooks, and links.
When you hover over a particular project item in List view, you will see a speech bubble icon for adding comments.
If a project item has existing comments, the comments icon will display a number representing the number of comments posted on that item. The icon will display green if you have any unread comments.
Hovering over the icon will give you a quick view of the most recent comment. You can mark the comment as read, add a reply, or view all comments on the item.
In Table view, the comment icon will be displayed to the right of any tasks that have existing comments. Hovering over the icon will show you the most recent comment as well as options to mark as read, view all comments, or reply.
You can see all comments across all project items in the project's Comments tab.
The Comments tab can be enabled or disabled in the project's settings. Only project administrators and above can access the settings.
