This is (kinda) brought up from another topic.
Since we can not change our own titles all too easily, wouldn't it be fun to get to change other people's titles?
It'd be neat to have some kind of contest with a daily winner. Whomever wins at the end of the day gets to change the title of anyone on the site. If somone has changed your title, then to get it changed back, you'll have to win the contest and change your own title.
But I don't have a clue what the contest would be...
