I'm (still) here: Astral Dynamics Down-Under Community
Have been there for many years. It'll be pretty much my only forum now, because I'm really not interested in joining any more online communities.
By the way, don't let the name fool you. There's a lot more spirituality stuff going on there than just the astral projection stuff. I've been a member there since 2007, and I think I've only talked about the topic of astral projection half a dozen times or so (out of thousands of posts).
It's a small forum, fairly intimate, but it might suit some of you. You're welcome to check it out, anyway.
