I received an email from someone telling me I have won a lottery of a great amount of money. Over $500,000.00. I am to send to Nigeria $100.00 by Western Union today. The man told me by email that this money is in the form of a bank draft which I can cash at any bank. So far they have not asked me for any banking information or any identification. Is this a legal activity? Need to know an answer before 10 m Iowa time.
