Description: Noosfero is a Web platform for social networks. Besides the regular social network features (such as friends and communities), Noosfero offers a full-featured CMS, making every user or community profile a complete Web site with several types of content (including text, image gallery, blogs, and file uploads), RSS feeds, agenda, the possibility to set custom themes, and other features. It is also possible to run several independent social networks within the same Noosfero installation.
