Matt:
How 'bout adding a newbie post at the top of the ski and nsg forums that has the FAQ - make it sticky, and title it something like (BEFORE POSTING READ THIS).
I know 80% of the people won't read it anyway, but for the 20% of the people that do, it will cut down a ton of crap posts asking the same questions...
You could include stuff like how to use the search feature, how to find trick tips, where to post questions about ski equipment, etc.
