I have probably the single greatest forum game idea the world has ever seen.  I cannot share it yet(or I might) because it is that good 

 While I was researching to make sure no one else thought of it I found this little game so i thought one round of it could be fun..Note: THIS IS NOT MY GAME IDEA. I am holding that secret until I can develop it. 
so basically in this game you make a sentence from letters the last person posts...so say last person posts
(at least two vowels must be present)
AHJOHP
I would post 
A High Java Object Hates People
then I would post the next letters 
HETULA
and the next person makes the phrase and posts new letters
