This project is a multi-frontend social networking site. Users can read information that is created wiki-like and imported from external sources. External sources will be at a beginning an RSS feed. Information will be classified according to the community where it is published and the system will assign tags to them.
Users will have an unique profile that allows them to access different communities. They will be able be able to choose who do they want to share their profile with and what information they publish will be showed publically.
The system will keep statistics such as most viewed articles and will allow the articles to be viewed within different communities as "related content". In each individual frontend, users can comment and rate information.
The site by itself has to have all the typical functions of any social network. Messaging, groups, forum, etc. It needs some special care with the privacy settings and that feature could be exactly as facebook is doing it right now.
See attached document for details of one solution proposal we received. It includes the customization of a WPMU installation and the creation of several plugins.
