Module Link: http://drupal.org/project/themekey Who: This module is for technical users that will be setting up the site. It's configuration can be complex and you have to understand Drupal fairly well to make the best of it. What: The theme key module allows you to change the theme on a variety of trigers like path, user id, etc. You will need to install additional modules to tie into things like taxonomy. When: Use this module when you need to change the page for a page, section or any of the 50 or so other triggers. I'm still not sure when most of the triggers would come in handy. Where: The settings for this module are found in the site configuration section of the admin back end. Make sure that you install the associated UI module or adding rules might be a problem (as in you can't). Why: Sometimes you just need part of your site to look different for whatever reason.
