I won't do a top 3, I think its unfair to people and it will degrade them. I reconized this few poeple as scripters: ScreenName, Ningnong, Falcor, Kai (Doesn't help much ;-( ), Jagen, Jeff, and Angel. For levels, I think that right now I don't think anyway has very good levels =/ I hardly ever see a nice level no more.
Newbies and hackers are not needed. Gani's, I only know of karsh, and they are good.
GFX... I liked DV, Kawaii, and Chibi's.
