Hi. My guild uses the xenForo forum base and have a feature on the front page named Recently Active Threads (and I'm assuming that it's a part of xenForo, and not handcoded. if so, please disregard my bugreport). It is supposed to show the three most active threads, and indeed it does - given that you have priveledges to read the subforum it was posted in. This leads to sometimes one or two threads showing up, where three should be visible, as you lack the permission to read the third/second thread. This also alerts users to when things have been posted in forums that they do not have access to, or even that such forums exist.
