Finally! A freelance job that pays more than $15 per article! In a nutshell, WorldStart.com wants computer how-to articles aimed at a beginner audience. Here's the pay rate according to the site:

400 word article with screenshots= $45.00 or without $35.00 screenshots 800 word article with screenshots= $55.00 or $45.00 without screenshots 1200-1500 word article with screenshots= $65.00 or $55.00 without screenshots  The downside is that they buy all rights. They are open to negotiation, though.

This would be a great site to build some tech writing clips with. It's a lot better than going with a site or magazine that pays you $5 an article.
