The combination of WordPress and BuddyPress is a powerful and complex mix, it will take you some time playing with all of the features in order for you to come up with your ideal site. In this article I would like to take you through the basics of getting to know your site and customising it for your purposes, in future articles I will cover adding additional features to your site in order to further customise your installation.
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.
