If you post a new thread, and haven't yet got any replies, the main page still says that the last "reply" was in some other old thread, and not in the one you just created. Make it show the latest post in any given forum.
The recent change to making Last Reply mean "The Last Reply" was intended to be a stepping stone to allowing us to show on the Forums page something along the lines of Most Recent Thread: XXX, Most Recent Reply: YYY.
Is this something people would find useful? Or would the preference be just "Last Post" which could be either a new thread or a reply to a thread?
