BuddyPress.org

Hey,

I am looking at using BuddyPress for a project but it has the following requirements is it possible I am looking for something like Ning.

I need each member to need to be accepted before they are allowed to use the member only area – they need to fill out a few specific questions when they join is this possible?

I need to be able to have 2 dictionary style listings a-z etc would a wp plugin work?
