You and your colleagues can comment on a specific task. This helps you to have all conversations related data protection matters in a central place. The screenshot below shows the initial task setup. 


And here an example with an added comment. 

You can edit your own comments by clicking on the pencil icon next to your user name. You cannot edit other users' comments with the exception of sub-task lists. For instance, if your colleague defined a set of sub-tasks (like in the example above), you can mark the checkbox in the respective comment.
