Graduation thread

I don't know if someone already has suggested it, let alone if this is even a useful idea, but what the heck: how about a graduation thread, in which people can post their mastery attempts and other people, who have already progressed beyond this level of mastery (better yet: the mods or coach himself) can vote if someone really mastered the progression by liking a submission post, e.g.?

It's called a form check and people do it all the time.
