i'm new at this.
Great ideea! I'll stick around for a while, looks like there's much to learn from you, guys. At the moment I know little about source code and hacking...but I am more willing to feed my curiosity than to spend a week on a deserted island with three gorgeous blondes. Hugs and kisses!
