This article is going to take you through setting up BuddyPress for the first time. It is geared towards people trying to set up Social Networking sites with features similar to those available with Ning or other hosted Social Network providers, as such it assumes that you will want all of the features of BuddyPress, plus a few more (well, a whole bunch more!).
Within BuddyPress, the Xprofile is the Extended Profile, information from which is what you can see when you view the Members>>Username>>Profile page. It is Xprofile fields that are completed when a member signs up for example. The registration page gathers data for the Xprofile “Base” Field Group. Other Field Groups can be added by Admin which are not set up on registration but will also be displayed on the members profile.
