Too late for that, the prizes are supposed to have been awarded already.
If anyone didn't receive their prize, submit your username and uid in this thread and we'll check it out.
If you were gold member, your gold membership has been extended with the amount of premium days you won. That can unfortunately not be changed.
However, GM is actually a better membership than premium in every single respect. Though I suppose some people find it more prestigious to have premium membership since it's more difficult to come by.
