where can I find a link to create a Nerd Herd ID Badge?

sorry I'm a bit late in the day in asking this question, but I'm a UK fan and only recently got back into this after it got taken off terrestrial tv (Idon't have satellite tv.) Sadly I've only seen the first 2 Seasons!!! (yes, I know, I must invest the the DVD Box Set so ALOT of catching up to do.........!!!)

Thank you
