is it possible to have more than one active theme? Basically what I'm trying to achieve is another theme that has none of the extra CSS/JS output by Drupal modules -- this would only be used for E-Newsletter display. I see the "default" setting for a theme, but how would I apply certain content types, etc to a specific theme? I've searched a bit and am stuck in the mud at the moment. Any help would be greatly appreciated. Thanks!
