buddypress features don't seem to be working.

Hi I am sorry if this is a duplicate post but I searched and couldn't find anything relating to my problem.
I have a few question all related to the members features of Buddypress.
have installed the lasted wpMU and buddypress.

1. I have added a few members and I can't figure out why they are not listed on the member page. Do I need to use the Member Directory Plugin to make this happen? I

2. I have been testing the "Add Friend" feature and have sent friend request and received the notification that I have a Friend Request but I can't seem to figure how to accept the request? I have search the BuddyPress manual at https://premium.wpmudev.org/the-buddypress-manual/making-friends/, but it does explain much.
