There's a very good place to check for hoaxes (BEFORE you e-mail all 700 people in your address book) here, at F-Secure Corporation. They also list chain letters. Folks, one rule of thumb is, it's a chain letter/hoax if it says to send it to everyone you know.

I was curious about how many people these things go to. I did the math. If each person who gets it sends it to 5 people, and the mailings only happen once per day, at the end of the 10th day, the message will have been sent a total of 2,441,405 times. I'm guessing in real life, these things have a much shorter turn-around time, and people mail them to more than 5 others. I guess I don't have to wonder why the internet gets so slow at times.
