Right...
Just had a look around your site..
You may wish to consider a few points..
On the index page. you should do 2 lines of 3; Not 3 Lines of 2..
This would mean increasing your div / table (didn't inspect the source) width, but in turn making it a greater pleasure to read.
Also, There's a local file inclusion vulnerability in your pages.
If you sent over the code you use for navigation:
include($_GET['id'].".php");
Kinda thing, I'd be happy to fix it for you :)
