My cousin (supposedly psychic and hates it), my aunt and my grandmother used one a few times to talk to my uncle mark (killed in a car crash before my cousin and I were born). They are not the type to BS, and they said it worked. They used the white candles and all to keep the "bad spirits" away. I've been meaning to ask to join them, but I haven't gotten around to it.

My cuz talks to Mark even without the board... sees ghosts and crap in old houses too. I think some of that paranormal/ESP stuff runs in my family.
