Sadly, after doing some searching yesterday, I could not find "active" groups about this subject. This is sad. There are communities, but not active right now, weeks ago they were. I think there is the option of Google groups (I just subscribed to one, very active it seems) and maybe I will check Yahoo Groups but prefer to first see about this group and decide later. The group is alt.dreams in case you would like to visit. You must first go to groups.google.com and then look for it.
