Make Money Fast
David Rhodes}}Make Money Fast (stylised as MAKE.MONEY.FAST) is a title of an electronically forwarded chain letter which first appeared on the Internet in 1989. It was widely distributed throughout dial-up BBSes, Usenet newsgroups, and email. In anti-spammer slang, the name is often abbreviated "MMF".
The emails were a form of pyramid scheme that involved sending small amounts of money to the postal addresses listed in the received email, then adding one's own name and address to the list before sending the email on to others. Provided by Wikipedia
