[quote name='quiznosrox']I signed up with about 35 different email addresses, got a confirmation email for all of them but only won on one of them. The email with the code came about 20 minutes after the confirmation email, so my theory is, if you have the confirmation email and you didn't get a response, you will most likely not win anything. Use new emails and sign up again.[/QUOTE]
Or, if you'd rather, only sign up once as to give your fellow gamers a fair chance. That'd be my suggestion.
