March 16, 2010 - Update :   Within the month, Prof. Siebert will no longer be using his AOL email address.
March 13, 2010 - Update :   This last week, an attempt was made by 419'ers to scam money from Prof. Siebert's friends. If you have received an email from (note the extra 'i' in the address), please disregard the fraudulent communication. The fraudulent email claims that he is stuck in the United Kingdom and needs $3,800 to get back home. This is an impossibility since Prof. Siebert never travels overseas without his friends, family, and/or grad students. How this happen is grounded in the fact that his AOL email address book, which at last count had some 350+ addresses, was hacked and stolen by one of these 419'ers. So, if you get an email from, please forward it to,, Western Union's Fraud Hotline at 1-800-448-1492, and/or the FBI's new Internet Crime Complaint Center.
