yea, character name will work as well. But alot of idiot kids now-a-days think its cool to mispell things and use LEET speak...yay how fun.
So, they use zeros in place of o's, and j's in place of i's, and all sorts of other idiotic things because then dont know how to speak and type properly, so I guess this is their way to not mess up. Hard to messup something thats supposed to be wrong in the first place.
