I am not clear how bbPress works with a site. If I have member only pages (which require a login) where I intend to install bbPress, will my members have to login a second time to use bbPress?
Will that they then have two accounts to deal with? Most of my users are older and not tech savvy. They need things to be simple. They will not self register. We will have a controlled set of users not open to outsiders.

bbpress uses wordpress login, so they only need to login once.
