ug, i made a post and the forums crapped up on me. well, what you need to do is vote on 5 submissions, then click the link where it says CLICK HERE TO DEPOSIT YOUR EXPERIENCE, then you should gain 10 exp. you can only get 10 exp a day, saddly, so it takes a while to level up, especially after level 9. if you're not seeing the link, then something must be wrong.
try reading this in the FAQ's the FAQ's contain the answers you seek :p
