For the past few days (couple of weeks maybe) I've been notocing that on the main page, there's a list of the last topic / post in that sub forum.
Usually it has the name of the thread, and the poster:
Re: drop the dead donkey by: bjorn.
Often now, the thread title is missing, so the entry is:
Re: by: bjorn.
No big deal, but something is amiss.
