Phpnuke is a web based automated news system. The administrator has total control of his web site, registered users, and he will have in the hand a powerful assembly of tools to maintain an active and 100% interactive web site using MySQL databases.
The system is written in PHP and has been released under the GNU GPL
It should be noted that PHPNuke has a dismal security history. Use at you own risk.
There is a spin-off of PHPNuke called PostNuke. Sadly is seems as insecure as the original.
