Comments can be used to provide feedback and help describe an issue by allowing the team to better communicate and discuss the context of the work item. The comments area is located between the properties and history tabs in the edit issue overlay. To add comments to an issue you must first have permission to edit issues.
Comments are displayed chronologically with the oldest at the top. For each comment the author name, the picture of the author, and the time when the comment was added are shown.
To add a comment you need to enter it in the blank area at the bottom of the comments list. The comment will be saved after Submit button is clicked.
Comments cannot be edited or deleted once they have been added.
