lol... I'm in the same situation and was actually thinking of starting a thread like this! I always sucked BAD at skating, and I was really surprised when I seemed to be picking up snowboarding pretty quickly. My greatest moment was ollieing onto a curb back in high school (only happened twice).
I used to try to ollie with my front foot starting in the center of the board. A couple days ago I tried doing it with my front foot closer to the bolts, and it seemed to help a lot. I landed 3 stationary ollies in a row (remember, I suck so that's big for me). Gonna try it while moving today.
Anyone know any good skateboard forums?
