I've been trying to find out the proper process for uninstalling / deleting themes from Drupal 6. It took a while, and I couldn't find a thread dedicated to this topic specifically, but I did find some information buried within a related post. I am re-posting what I found here in case anyone else is trying to do the same:

"Posted by VM on October 7, 2010 at 10:06am

There is no uninstall routine for themes. If they are disabled they can be deleted from the file system. If you delete a theme that is enabled and set as default, deleting it will result in a themeless site."

Hope that helps.

If you'd like to add a book page in drupal.org handbook, you are allowed to do so.

I know there's a record in the system table.
Anyone know if it gets cleared by update or clear-cache?
