UC Berkeley guest lecture advice

Hey all, been a long time since I've been here, but a friend of mine is a professor at UCB, and he asked me to give a lecture on Scientology for his "Cults and Secret Societies" class this fall.

Basically, I need some interesting ideas for a discussion, maybe a good power point (if anyone has one of those). Also, some comparisons to other cults and secret societies' practices would be handy.

Any help you guys could provide would be GREAT!

Well you can tell it's been a long time since I was here. Sorry. I'd love to hear how it went though!
