Posting Wars

This Idea just sort of came to me, but
What if that members got to chose one of two teams (Shinigami+Arrancar) and Certain members would hold positions on these teams relative to current positions in which its bassically a war to see which team posts more (without double posting of course) and say the prize could be to something on the web page changed to a character that represents the teams like if team Arancar won, something would be a hollow or arrancar or one of the "renagade" captains and vice versa. maybe even a background for the forums, if that isn't too difficult.
Oh, and it's only limited to a certain area of the forums. I think that if it was through out the entirety of the forums, it'd be kinda hard to manage.
