(co)maintenance

Sure. Have you tried the ThemeKey module with TaxonomyTheme for Drupal 6? Basically ThemeKey does all the heavy lifting and TaxonomyTheme is a "UI-only" module now, which makes it easier for unexperienced users to manage theme assignments for taxonomy vocabs/terms.

I suggest that you start helping in/with the queue. You dont have much of a user history on drupal.org, what means I'd prefer to not grant you access to cvs for the first few days/weeks.

I didnt have time to document the changes and to write a nice README. However, ThemeKey tries to solve all the issues that arised for TaxonomyTheme 4.7/5.x (for example, handling of multiple taxonomy terms and weighting, etc.). During the last two release cycles TaxonomyTheme developed from a simple taxonomy-related module to a more sophisticated theme switcher including the ability to use a path-based assignment pattern. ThemeKey now shifts the focus of TaxonomyTheme back to "Taxonomy", although the module is not required for experienced users as ThemeKey provides all the functionality itself.

@valthebald: Are you still interested in co-maintaining this module?

ThemeKey is far more flexible, while 6.x Taxonomy theme is fully functional for backward compatibility purposes

That's what I wanted to achieve. Thanks for your feedback.
