Can you explain why you would need this?
Sometimes user get/give wrong feedback or they change opinion. So they have to write to somebody via messages. (Usually to moderators, but only admin can change, delete feedback...) Just suggestion, resolving via messages is also ok.
Maybe I am doing someting wrong, but now if I got feedback, I have to go to user profile > add feedback > fill topic name etc.
after I read feedback click on give feedback back and chose rating, write comment and done.
