I wrote a script almost a year ago to help me stay on top of site-wide validation for a few projects I'm a part of. Recently I integrated this script into a website that I'm now sharing for free with the world and would like a few beta testers to give it a shot and provide feedback before I open the flood gates. So, anyone who cares about validation and is interested in a tool that validates an entire site (not just a single page), sign up at http://freesitevalidator.com. I will be approving accounts manually until I've verified the server is not going to blow up under heavy load. Also, any feedback or suggestions are more than welcome.
