Most of the sites I list here have some method of gaining credit for referring your friends, co-workers, and complete strangers to their site.  Look for your personal “referral link” and pass it on be promoting it on forum sites, blogs, and your own web site(s) (when the other person clicks on your link and signs up, you get the credit.)  If you are a web site owner you can make extra money by advertising these sites using an “affiliate program” (if available.)
