Does this BBS give the option for an anonymous poll embedded in a thread? That might be interesting.
I am a night person and really enjoy being online late. This board doesn't seem to get much activity after 11 p.m. EST in the U.S.
For an unscientific subjective opinion, using stereotypes (the universe revolves around the U.S., old people go to bed early, etc.), the dearth of late-nite posting would suggest most of us are well over 50
(Before I get flamed, that was a JOKE.)
