Hiya Geranium,
No specific forum, but you could search the Study Groups area...
I have the deck myself, love it, but haven't used it much for face to face readings yet.
There was a DOM study group. try an advance search for it in specific forums. I burned out and dropped out for a while around the time I was participating in it (I have a DOM deck) and never found out what happened with it. Maybe WhiteRaven can tell you. Try PM'ing her.
