http://darkscaler.com My site is a tutorial site powered by pligg type software. Users may submit tutorial links or can submit their RSS feed. When a user submits their tutorial RSS feed it is manually reviewed and then added to the database if accepted. Any updates to the RSS and therefore tutorials will then be automatically updated on the site. My site has sparked an interest among the big tutorial sites and they have submitted feeds. The sites has only been around for a couple of weeks and we hope to grow. Please review about new features, how to improve ease of use, how to improve the design. I am looking for a partner on this for SEO, etc if you are interested PM me. http://darkscaler.com
