These are residual writting sites. Residual means that you write the article, and publish it to their site and you earn revenue based on the ad clicks your article gets. These are great to have for long term earning.

EHow: EHow is a website where you can register and submit How To articles. The format is simple, and you can submit as many articles as you would like. You earn residual income based on the amount of article views. There is some money that can be made with this, but you have to be willing to submit allot of articles. I will warn you that they are a little delayed when it comes to updating your profits and sometimes your articles. This is also a good site for those who are trying to get into freelance writing.

Suite 101:  So far I have been having pretty good luck with Suite.  Once you get their format down, the possiblities are endless.  I do have a blog following my progress if you would like to check it out click here.
