I've been a member for many years (and am a moderator) here: Astral Dynamics Down-Under Community
There's a sub-forum for manifestation/reality creation, as well as a variety of other metaphysical interests (spiritual evolution, energy work, astral projection, dream interpretation, etc.).
Please drop around and see if it suits your needs. It's a pretty small community, but very worthwhile, I've found. It's been my "spiritual home" for years.
