Someobdy suggested I used the external pages plugin to load local files, this is a fine idea. I have loaded the plugin and added a few files but it fully takes me out of my GL interface. I wish for the header to remain intact. This same person mentioned some code to put at the top of each html file which will make the external html file appear geeked. What is this code? AM I on the right track? Thanks..

The templates that come with the plugin have settings you can change to allow your page to appear as a part of the rest of your site or not. Check those out - they are found in the externalpages_template folder.

What's the diff between geekphphtml.php and phphtml.php?

Geekphphtml lets you choose whether to have the right and left blocks on your external page and the other one doesn't give you that option.
