Woodie:
Glad you like the style! I worked hard on it.
To make it work on the main page in your admin options go to the "STYLES" area. There you will see two styles listed. "Default", and the techforums style.
Click "properties" next to the "Default" style. One inside you will see a drop down box for both templates, and Replacement set. Right now it should say Default. Change them both to the tech forums template set, and replacement set.
Then click save and that should be it.
