Hello Friends,

Brand new to BuddyPress.

I am using a Child of Twentyeleven WP version 3.6.
SITE:

I have installed BP, (BuddyPress) but have not Activated it as yet.
Because I need to use my Child of Twentyeleven but make use of the part of BuddyPress which will enable me to create a my own sign up member area, is there a specific method of installation I should adhere to, or tutorial which will guide me through this procedure?

Many thanks in advance for your help.
