After a long hiatus, the “Ask STEPH” formerly “Ask nextSTEPH” section is back.
This question comes from Ja-Naé Duane:
What is the difference between WordPress MU and Buddypress?
WordPress Multi-Site (formerly WordPress Mu) allows an administrator to create multiple WordPress sites under the same installation. The administrator would activate multi-site functionality, therefore creating a network of sites.
BuddyPress allows you to create a custom community. Think about having your own out of the box social network with the foundation of WordPress.
