Also have a hosting domain at http://forumhosting.ca - there is a site on it but it is not active as it needs a billing system (it was using WHMCS from http://whmcs.com/ so if you purchase a license or pay monthly then you will already have it integrated into the site design!)
http://gamingtalk.org - started to develop it. Does have a working cheat script installed and integrated into site layout as well as a gaming cms for news, reviews and previews.
http://graphicsdirectory.net/ - has a directory of graphics sites, a download script, gallery, image hosting and tutorial script installed and integrated into site layout.
