As a user in charge of reviewing and approving documents in Mediusflow, I would like that when I'm posting some comments, the responder should have the ability to reply to the comments so if I ask comments to multiple responders I can easily see the different answers along with the original query.

If the responder received the comment per email because it has been mentioned in it, he should be able to reply to the email and the reply will be added to a reply to the comments.
