Here's some information about this site. First of all, the main thing is that it's running on CMS Joomla!. I must say, that I really like the way it's working, because I was a newby and was amazed by all the components en plug-ins you can find for this site.

I built my own template with help from other live sites and the template tutorial 

Here's a list of extensions used on this site:

Core: 

• Basis: Joomla! 1.0.12
• Tutorials including one tutorial for building your own template.

Plug-ins (Mambots):

• Video Plugin to play .flv, .swf, .mov, .mp4, .wmv, .avi, .mpg, .mpeg, .rm, .ram, .wma, .mp3: AllVideos

Components:

• Multi-lingual component: Joom!fish
• Explorer for Joomla! files: Joomla!Xplorer
• Guestbook called EasyGuestbook
• Gallery 2 from Menalto with Gallery2 Bridge to Joomla!
• Search Engine Optimizer which generates search engine friendly url Open Sef . Currently this component does not work correctly together with Joom!Fish. But I did like the options with this component so when a new version comes out, I will definitely use it.
