I saw some site uses SHTML, May I know what it is? :P

I hardly know, but I think its HTML From the server, and the it gives server's options and actions to do without having to know any knowledge of PHP and MySQL, but thats just my guess. It works great with CGI Perl Python etc works great for that kind of stuff.
