I had a membership card in a fan club once...it was New Kids on the Block and I was 13 years old!!
GEEZ...who cares about a stupid card with a number of it (OMG, I'm number 6!!!!!!! Ah, crap, I'm number 81.) saying you belong to the club, I think they could have sprung for a free shirt (even if it was WHITE!!) or a keychain that could be mass produced for like a hundred bucks or something.
I mean..COME ON...JT should have done research on OTHER fan clubs if he wanted to see what kind of things to do...
