I'm not sure why I didn't get my D:OS kickstarter badge, or the weresheep one (I did donate the fee!). Oh well, forum badges aren't everything ;-)
Do you use the same mail address here than you use on KS? If not, just send a PM to Raze and he'll merge the two and give you your badges.
You also have to "activate" the badges manually on your account settings. Maybe they're already there, waiting for you?
