For a ton of info on Sylvia Browne and the James Randi Educational Foundation go to:http://www.randi.org/sylvia/index.shtml
For those too young to know, in the 60's and 70's James Randi was one of the world's leading professional magicians, performing as the Amazing Randi. For the last 20 years or so, he has devoted himself to traveling around the world exposing phony "psychics", "spiritualists", "faith healers", etc. His first major success was Uri Geller, who claimed to be able to bend spoons and forks using "mind power". Randi would follow him on all the talk shows and demonstrate how it was a simple parlor trick. Geller hasn't been heard from since.
His foundation has $1 million in escrow for anyone who can prove to a panel of scholars and experts that they are a legitimate psychic. So far, no one has ever claimed the money.
Very interesting guy with a great website.
