Subster Rejuvenation v.021 is a WordPress plugin that turns your categories into subdomains. We are now running it on this site. I’m sure there might be a couple of bugs, so post comments if you find any.

Update 1-28-06

v0.21 is a major rewrite. Here’s a list of the new features:

• Sub categories are now nested properly. So urls will look like http://maincategory.domain.com/subcategory/post/
• You can now make subdomains out of static pages. Sub pages will also be nested the same way sub categories are.
• You can now tie a static page to a category subdomain. http://maincategory.domain.com/staticpage/
• You can now use separate themes for individual subdomains.

The only real downside of v0.20 is the fact that it is now no longer compatible with WP 1.5. If you want to run this version, you will need to upgrade to WP 2.0
