[quote name='cheapskake']I just won a little big planet 2. Where do you register your mailing address? When i first registered, they only asked for my email address and my name/zipcode.[/QUOTE]
The *first* time you win a prize (even if it's a digital download) you have to put in your address to claim it. Then, it's tied to your email account on future wins.
So, you must've won something prior, or it glitched. Hopefully, it was the former.
If you're worried about it, send an email to PrizeLogic and hope they say/do something.
