When a user asks a question to someone else within a comment (ex: @Jessica should this be changed to match the other piece?) Jessica is sent an email notification that someone has sent her a comment. However, if Jessica's stage isn't active she's not able to respond to the comment. This makes things quite challenging as Jessica's response could effect the rest of the current persons review. I'd like to add a feature where when someone is asked a specific question and a notification email is sent to them they are allowed to respond to that comment within the proof.
