you'd think they'd send the emails out all at once though (as it sort of sounds like they just did).
and besides, while i dont want to go and turn the Xbox around to get my S/N again, i did not use a gametag when i last entered, i wonder if that would invalidate my entry, or if entering again with info i know have will not invalidate it.
just out of curiosity, for those that already got emails, you didnt need a gamertag to get it right? i mean, they gave you codes in the email to use right?
