BuddyPress will extend WordPress MU and bring social networking features to a new or existing installation. |
BuddyPress is essentially a set of WordPress MU specific plugins. Each plugin component adds a distinct feature to BuddyPress and only handles functionality for that specific component (for example, private messaging). BuddyPress also has a core plugin that all other plugins require, it contains shared functions and performs the basic modifications to the WordPress MU interface.
