The Comment function helps team members to collaborate with other team members by communicating, discussing, or updating their work status. It captures all the communication and updates of a task.

How to input a comment

You can input a comment on a registered issue with the following steps. 

  1. Go to a registered task page.
  2. Click on the comment bar at the bottom of the page.
  3. Input your message in the comment box.
  4. Click Submit to post your comment.

Tip: The Comment function supports emoticons and other basic text formatting such as bold, italic, bullet list, number list, quote, code, etc.

For comprehensive formatting rules, you can view them by clicking on the ? icon at the comment box.


Notifying members in a comment

You can notify members or teams participating in the project so that they are alerted about updates or communications within the task. 

To notify members or teams about your comment, use the mention function (@username). Notified members will receive notifications in Backlog. 


Attaching file in your comment

You can attach a file or image in the new comment. To do so, at the left side of the comment box, click on the clip icon (attach file) > drag & drop files / select files from your PC folder

An image tag will appear in the comment input box after you have added the attachment.

Tip: If a comment has been posted and you wish to attach the file in the posted comment, go to the comment, select more icon (...) > select Attach file.
