Hey everyone I've started a project called Diviniti Site Engine. It is an opensource content management system. It's not a portal like a nuke but rather a system that allows website administrators an easy way to update their website and provide some interactive functions.
It's designed for that middle crowd of people who enjoy working with HTML and perhaps CSS but don't know any PHP code. People who want to be able to layout their website as if they were just building it with html files but can insert special powertags that pull interactive elements (like messageboards, statistics, polls, articles, ect) into the pages.
With this system you can build personal websites or full blown member driven sites. It all depends on the modules you install and the settings you set.
Currently we are seeking more PHP programmers for this project. It is pretty large but has great potential.
