This weekend I've made two new tags available for articles on the site - "build_site" and "motorsport".  When setting up the site, I was sure I want to discrimate on the basis of marque, I wasn't sure what else would be required.  In particular, the "build_site" tag will mark articles with web sites that will help those building their cars.  I won't be applying these tags retrospectively (unless I've a quiet moment in work).

If there are any other tags that people would find useful, let me know.
