Are you a hosting affiliate?
I was just thinking about it because some of the webhosting commisions are out of this world. For example at hostgator, you make $50 a commission if you refer 1-5 people a month. If you refer above 21 people a month, you make $125 per commission.
Crazy. Someday I'd love to take part in that, but I'm not ready for it yet.
Just when you think you've got it all figured out, someone changes the rules.
