Re: Where are the forums located?
Have you integrated bbPress with WordPress? Or have you just installed WP for the first time? To share logins with WordPress ( BuddyPress does not handle logins. That is WP’s role), bbPress needs to be configured with what is termed deep integration. This is not a simple task.
Below are some links with more details. Read the first link to decide if you truly need bbPress configured in this way. Perhaps the way BuddyPress uses bbPress (providing group-based forums instead of one, overall site-wide forum) might be acceptable for your site. If so, then you’ll have a much easier time.

Deep Integration (I have no idea if this information is still accurate for WP 3.0):
