"that's a smith and wesson, and you've had your six"
How about a kind of feature to let everyone knows the Geekversary of users? Something like today is 3 years that user x, y and z are on the BGG? or today user xpto is a BGG supporter for n years?
Just a though.
BGG doesn't accurately acknowledge the real date of a big chunk of user registrations. The Geek went through some sort of batch DB migration in 2002 and a lot of people have dates that correspond to far after they actually registered.
