I noticed that according to the rules you are allowed to share your own free scripts, so I decided why not have a little shameless self-promotion
I just released my open-source free webhosting script, called Multihoster. Multihoster is an open-source free webhosting system, written in php, with a mysql backend. It enables any webmaster to be their own free webhost, like Geocities or Angelfire. With more features than its pricey competitors, along with the unique ability to be run on a shared server, and a price tag that's hard to resist, Multihoster is the perfect solution for any webmaster that desires to be a free webhost.
Key admin features include: bandwidth and space are automatically monitored, an easy installation file and admin control panel, the option to put ads on user pages, and MUCH more. Key user features include their own directory with unlimited subdirectory levels, a simple but in-depth control panel, a pop3 email address (if the admin allows), their own detailed stats page, and also much more. There is also a built-in directory system so users can share their site with the world.
Those are just a few key features, for a full feature list go to
