Sorry to shoot you down bro, but I'm pretty sure it's just members who are not at home and are on Newschoolers.com and haven't bothered to log in, or people who haven't bothered to log in period.
does it matter if there are more guests than members? the only thing worse than attention is no attention, i see not problem with guests, i expect a fairly large percentage sign up. it is not as if it costs anything
