Ok heres the deal. I have been working on a squadron website for quite some time now and realized that html just isn't the way to go. It seems to be dead so I want to shift towards a PHP ran site. My site is really simple and I am sure that my question is going to be retarded but I have been toying with it for far too long. At www.puggo.com you can see my website. The goal is to keep everything in union except for the text in the middle of the page which will change when you click on any of the links. Also the menu on the lefthand side needs submenus. The problem I face is that I want to have a "Recent Articles" section and it just seems difficult to figure out how to keep a template for every page. It seems if I make any change I have to change all the pages which is a lot of work. Anyone got any solutions even if it isn't php? Thanks for your help in advance! -Derek, the confused one
