So a while back I signed up with this site called articledocument.com and after several weeks of wading through red tape involving tax forms. I was finally approved to start submitting work through them. Right now all I can submit are 300 word blog posts on a particular subject chosen by them, but eventually I'll be able to get paid for proper on-line articles. I'm mainly posting this here because the blogs pay royalties; the more views an article gets, the more I'll make.

I concede it's not perfect, while the details said it was excellent for the information, everything else was average and that it cuts off abruptly.
