It's sad that it's eight years since this thread was active.....and the answer to the question still appears to be 'very few'.
One of the members in this thread, an online friend, passed over at a very young age in desperately tragic circumstances. Another is around as still am I.
So that's just thee and me presently, BJ - assuming you're one. Unless anyone cares to join us and declare that Modern Spiritualism is their persuasion too?
