Lets face it, FFA's are probably a waste of time. Your link disappears quickly on most, and they are not topic related. Still, they are attractive because of their ease. It's almost fun. And with this list of FFA's, you don't have to deal with old ones that don't work, or worthless ones that aren't even listed by GOOGLE. Last updated June 2007. PLEASE DON'T STEAL IT, but if you do, at least give us a link.
* = submit often.
