You know...I sometimes wonder who invites me to join some of the groups/websites that I get invited to join. I was invited to join a Yahoo! Group dedicated to some regional wrestling organization, so I joined it. I was invited to a Yahoo! Group about time travel research. I couldn't resist joining that one. I've now been invited to join CultZero. Who invited me to join? Was it just a random e-mail sent out?

EDIT:
You gotta love when a professor gets lazy when it comes to updating graphics on a website.
