After consideration, I agree that the two forum sections, one for "forum member self promotion" and one for "non-Hypnos activities by Hypnos artists" can be combined. If a Hypnos artists does a non-Hypnos album or video or soundtrack, they can publicize it in the "forum member self-promotion" area well enough. This should help clear up confusion about where postings should go.
I admit there remains some potential for overlap between the "forum member self-promotion" area and the "other ambient music" area, especially if someone's work is being discussed and they show up and become a member.
To me the key distinction is creating a topic to announce or promote your own project. If somebody wants to talk about Steve Roach, and after two pages of debate Steve shows up here to comment, that doesn't mean the topic is suddenly self-promotion. Yes, in many cases a topic ends up being "visited" by the person it's about, but I don't think that's a problem. The bottom line is that I think there's a big difference between some listener talking about music they enjoy, and some artist or label promoting their own project. That's the difference between those two sections. If once in a while some topic shifts from one to the other, it won't be a big deal to move it.
