How does one send/accept/decline friend requests from BP Social theme?

How does one send/accept/decline friend requests from BP Social theme? Is having Supporter and Membership plugins activated but somewhat unconfigured possibly keeping this from displaying?

A broader question--there are a lot of BP Social threads, one with about 170 replies -- is there any sort of compact, concise User Guide that I can give to my site users to help them get up to speed with BP Social privacy, friending and messaging features?
