This is what I sent out to many people in my address book tonight and I thought others my benefit from my *cough* experience.
If you are receiving this email, it is because you came in contact with me via email sometime in the last decade.

Please read this blog post by Westley Fryer for more detailed information: http://www.speedofcreativity.org/2007/09/07/beware-of-quechup-spam-scam/
My sincere apologies,
