Howto: Webpage
You can host your personal website at the shell. Just put the files in ~/public_html (this is a symlink to /var/www/users/username).
If you want a page to be served when the user asks for a direcory, name it index.html, index.htm or index.php If you have none of these files, a directory listing will be used instead.
You can view your website at http://<username>.blinkenshell.org/
PHP 5 and SSI is installed on the server. CGI is not allowed at the moment.
