Unfortunately, I won't be able to present "What is Paganism?" this fall, since I got a job in Kent. If someone else (especially an OSU student) would like to take over this topic, feel free. Here is a list of some of the more common Neopagan religions to get you started (ignore if it's not useful.)
Wicca - solitary vs. coven
traditions: Gardnerian, Alexandrian, Celtic, Irish, Eclectic, Dianic, Protean, Christos, Hexarian, etc.
