there is this thing called "php nuke" and you put it on your sever and you can make a site. i'm not sure how it works. coz i've never used it. but my friend has and it looks like this: http://lt-host.co.uk/tfl/index.php
oh ya forgot. php nuke can be downloaded at: www.phpnuke.com
I know all about php nuke and other such content management systems. After evaluation, none of them met my requirements.
