UTW Theme Compatibility Thing will allow the UTW template tags in existing themes to work with the native tag store in WordPress.
http://www.neato.co.nz/plugins/UTWRenderThing.zip has the latest version.
Copy the plugin to your plugins folder
Disable UTW, then enable this plugin (The two plugins share function names, so cannot run simulateously)
If you’re using icons in your formatting, there are a couple of extra steps.
Leave the UTW plugin folder on your webserver
Go to the Options > UTW Render Thing page, and enter a value for Base URL for Icons.
This plugin provides the functionality that the UTW_Show… functions in Ultimate Tag Warrior used to provide; except using the tags stored in WordPress. The formatting documentation for UTW remains largely the same for UTW-TCT (:
