Welcome to GreekChat, itsgreat2bgreek. ZZ-kai- makes some good points, and you might also be interested in the thread
Dirty Little Secrets.
But don't expect anyone to give you any specifics on any rituals, or to talk too much about " any stories of initiated members talking a little too much about ritual," or to make other than general, generic comments. Anything specific tends to raise red flags for lots of folks around here and, often, to result in a locked thread.
