Here's an idea:Forum Games (Anyone watch Idea Channel?)
I personally think that every forum should have a topic/subtopic/whatever-ever-it-would-be-called where users can play fun games based on forum mechanics.(No I am not talking about rp's. Duh.) 
If you have not been lucky enough to be on a forum that has a Forum Games let me explain it to you by lists of games to be found there:
-Corrupt a wish.
User posts a wish, the next user posts that there wish is granted but, something g goes wrong. Then user #2 posts their own wish.
-Question Game
A user posts a question, then the next user post the answer to the question as a question. 
Belt Game
User Posts a word, next user posts a word that starts with the last letter of the previous word.
That concludes my pitch, any questions?
