A tagged user in a deal note will not be notified if they are not a follower of that deal.

It is contradictory that when you use the @ tag all users are suggested, but if you choose someone who does not follow the deal, this person will not receive a notification. It would be useful if that person automatically became a follower of this deal and therefore also received a message about the note. I don't want to make every user a follower of everything to make tagging in a note work properly, and I don't think this is the intention.
