I have just installed SHP (http://www.sciurus.co.uk) on my 2 domains www.virtuaserver.dk and www.virtuaserver.eu and its basicly a simple but easy and fast Webhosting system that allows visitors to register a "domain" www.virtuaserver.eu/username, upload and edit files via File Browser and have their own website..

You can register and try it out, maybe host that website you always wanted.
This webservice will be free forever and atleast be opened for the first 100 people!
