I participated in the Forum, back in the eighties, as part of my ethnographic research of quasi-religious organizations and new religious movements. My impression, which does not constitute a statistically significant amount of data, was that it was one of the most boring and depressing experiences I've had. Really, it's remarkable how unpleasant it was, considering that I was not in any danger or pain. But do bear in mind that the plural of anecdote is not data, and that YMMV.
