Re: Where are the forums located?
Depending on whether you’ve turned on the components at Dashboard > BuddyPress > Component Setup, BP provides extended user profiles, an interactive activity stream, private messaging, user-creatable groups (with integrated activity streams, forums, and other functionality available via plugins), blog tracking, friend connections, and member/group directories. The toolbar at the top of the screen is one of the methods built into the UI for accessing these features. If you’re using a BP-compatible theme like the bundled bp-default, then you should also see tabs for Members, Groups, Forums etc near the top of your screen.
testbp.org is one place to see BP being used (for test purposes, obviously, but you can get a sense of the organization).
