I have a self-updated LiveJournal and belong to the Astral Society and Lucid Dreaming communities there.
Astral Society gets more traffic and a lot of newbie questions and generic posts about dreams. Lucid Dreaming has fewer posts and AFAIK not a lot of very experienced or knowledgable members. I have answered some questions and promoted the forum more than once.
great if any Forum members would like to join these communities or read my LJ. BTW I do not have any LJ codes to give out as I have run out of all of mine, sadly.
