Elgg is an open source social networking framework. It provides the necessary functionality to allow you to run your own social networking site, whether publicly (like Facebook) or internally on an intranet (like Microsoft Sharepoint). Elgg is used by universities, governments, non-profits, commercial companies, teachers in their classrooms, and individuals.

Elgg was designed with an emphasis on extensibility, privacy, and collaboration. It is written in PHP and uses MySQL as its database and jQuery for front end scripting.
