3) TechAutos is a site that covers automotive and technological (computing, etc.) interests - important news from each field is posted on the home page, along with special content articles and more, and the forums are open for members to ask questions, make comments, etc.
4) TCH link is in the footer of the site - visible while viewing any page on the site.
5) Any ideas on search engine optimization would be appreciated very much - I'm working to get metatags, etc. to work with PHPNuke, so that should be up soon.
