After a few hours trying to get a php if… else statement working I was finally able to extend the dynamic highlighting effect for the navigation panel into the blog, so if you are on the 2006 archive page the 2006 archive will be highlighted in the navigational panel.  I have also moved the header, search box, menu, and page footer for the main site into separate files, to make it easier to update them and to reduce the size of the individual pages.  At the same time I have converted most of the site to php rather than html, this means if I need to include something from the blog in the main site I can without any problems, the only part of the site that isn’t php now are the error pages which will remain asp for now.
