Just so this can be cleared up, the birthday badge is manually
awarded to users who have celebrated their birthday on Tgforums. If you have a birthday thread here and you haven't gotten your birthday badge, kindly PM tgfcoder
and he'll add it to your account.
We are working on designing a more automated way to do this but for now this is how it's done.
If your birthday has passed while you were registered and active on Tgforums but you didn't get a birthday thread, you may also PM me and depending on your level of activity I may still award the badge.
