BuddyPress.org

A new version of bbPress, 1.0-Alpha-4, was just released on bbPress.org which “Should fix issues that people had with integrated cookies with WordPress in 1.0-alpha-3 without reverting any new features in it.”

Not sure if this is related to any of our problems but it’d be advisable to upgrade and see if it helps.

Along with the cookie fixes mentioned above, this new release will also assign users a role in bbPress as soon as they visit the forums with WordPress cookies. Previously they needed to log in to be assigned a role.
