As described on the home page, I work with websites for a living. Due to the commercial nature of this and trying to maintain the corporate image, these tend to be quite boring sites but they are of great value to the people who use them.
This has taught me various things though. The first is that I never produce flat HTML pages, all of my sites are data driven by MySQL which is delivered to the browser by PHP.
This gives tremendous flexibility and allows the changing of the site content at the drop of a hat. Add to this the use off header & footer templates along with CSS and the entire look, feel & functionality of the site can be changed by editing a few files. This is why I'm always changing this site - because I can!
