Here's the websites of the advanced courses I mentioned at the meeting.
Disclaimers:
I know very little about the Hedonistic Enthusiasm course, but the woman who told me about it swears by it. I took a course similar to Zaluskys about 25 years ago and it was well worth it (but I was young and invincible then).
Judging by the dates listed on the websites, it may be too late this year anyway, but If there's any interest, let me know and I'll track down some more information.
