hmmm, interesting site, i wonder what script is it made of

It's easy to tell if a site uses JavaScript by viewing the source. In this case the pages are linking to JavaScript files.

The 'J' in Ajax stands for JavaScript. I do see the pages linking to at least one common JavaScript library that's typically use in Ajax applications. I assume the site is interacting with a database and we can call it Ajax.

Based on some of the URLs and the the way the source looks with all the table cells I'd guess there's some server side programming producing the code. The site is sitting on an Apache server so my guess is PHP is the server side language, but it doesn't have to be.
