I want to create a member section in wordpress. Only the members will have access to a directory & a forum. Now I can give these 2 links visible when someone registers creates a account .. thats ok

But what my question is can the same username/password used to login to the forum, as if the user needs to again register for the forum it would be 2 times he needs to register. In short using a single login for forum and member area

Bbpress uses the wordpress login, so they will have single signon.
