BuddyPress | Run your own social network
BuddyPress builds on the WordPress engine, (one of the world’s most popular, established and widely supported CMS systems that has a huge number of functional enhancements).
With the addition of BuddyPress extensions to the WordPress core, the application now supports advanced social networking features, for scalable, highly functional community websites.
BuddyPress is an open source social networking software package. It is a plugin that can be installed on WordPress to transform it into a social network platform. BuddyPress is designed to allow companies, academic institutions or any other niche community start their own social network or communication tool. BuddyPress inherits and extends upon the integral functional elements of the WordPress engine including themes, plugins and widgets.
As it is built on WordPress it is written using the same primary technologies, PHP and MySQL. BuddyPress has a range of features that will allow the creation of a social network application.
