Here's the page with Randi's Million Dollar Challenge information:
Million Dollar Challenge Application
Not sure when you saw this document originally, but according to the page here, some data has changed as of April '07.
Nowhere in the document, at least as far as I saw, specifies that the Randi foundation will only study certain people for certain phenomena based on their popularity.
Erin, even if you're not interested in the million dollar prize, then take the test, pass it and give the million bucks to your favourite charity. That way, everybody wins. Randi and his crew will finally have some sort of proof of paranormal activity under properly controlled conditions, your favourite charity will have a million-dollar windfall for, say, a home for abused women or children rescued from slavery in South America or Africa or the fight against AIDS... the list is endless... and you will be the one whose name goes down in the history books as proving, once and for all, that there actually is something to this paranormal thing.
Are those reasons not enough to try?
