Great idea Rhett. No way are we going to stop those hoaxes, but if we at least enlighten the people who send them to us, maybe it will slow them down a little, and make them think before sending on the next one.
http://www.snopes2.com/ is another great site for checking out hoaxes. They don't pull any punches if you want to send the page regarding the particular hoax back to the gullible person who sent it to you in the first place. It is also interesting to read just for the entertainment!
