Winners are notified via email. We send a winner notification email to the address we have on file for you - so be sure your email address is up to date. (To change your email address, click on the arrow next to your profile picture on the upper right corner of the page and choose Settings. There, you will find the Modify your Email tab/section.)
Every winner's notification includes a confirmation deadline - which means that you must respond to the prize notification by the date stated in the email, or your prize will be cancelled. So check your email often!
Members can also check the other rewards information in the Prize draws section on the website, which you can find by entering the Points Balance page, marked with a star, on the upper right corner, next to the profile picture. Any contest winnings that are pending acceptance will be listed in this section of the page.
