well obviously u know how to add stuff to your faves.. u already have one.
next try upload something,at the top of the A page, it says submit, open that, then select a file u want to uplaod, but make sure u did it, cause u can't use other people's stuff unless they tell you so XP
then make sure u put a title and selecta category, and then scroll down and finish it off ^^ then your done XP
