The site is completely xhtml and css verified and converted to and php coded. XHTML is basically the successor to HTML these days but allows for much more possibility's and is much easier to maintain, but semantic coding is more strict also. Which is good since it separates amateurs from professionals even more.
The site also uses CSS technology for the complete markup of the layout. CSS is the norm these days for proper semantic coding and basically most sites use it in any way or another. Finally all of the pages are converted and further enhanced in the php language for easier updating, implementing scripts and more. The mainsite also use 2 small mysql databases for the searchengine and rating functions.
I'm still in the process of making the site even much more dynamic in the future, but learning those things takes time;)
