Winners are notified via email. We send a winner notification email to the address we have on file for you, so please be sure to keep your email address up-to-date. (To change your email address, sign in and click on "Settings" from the drop-down menu next to your avatar.)
Every winner's notification includes an expiration date - which means that you must respond to the prize notification by the date stated in the email or you'll forfeit the prize. So, be sure to keep an eye out on your email!
