Sorry, this is more of a user issue than a discussion topic, but I'd like to know the answer. Several times recently, I've noticed that an old discussion topic has resurfaced in the list of Discussion items, even though it had previously rolled off the list of topics.
There must be a way to bring back an old discussion topic, even though I haven't seen a way to do it. I can't see any topics that have already rolled of the board. Am I blind?
