Indeedy, and a "Who's done best in the last six months" chart is, IMO, fairer than a rookie award. No reason you can't have both, of course.
Here's a wacky idea: have a TSC Awards 2006 topic with voting - categories like best 3D player in 06, best 2D, best newbie etc. Except people have to be nominated for categories by OTHER MEMBERS, rather than by one person or by themselves, and reasons must be given. Oh and we could have fun ones like biggest noob (still pccorby d'you reckon?), worst necromancer, most homicidal (naming no names on this one >_>)
