>Ah, I just saw that. So, when you click on the forum name, it resets the new message count. I was thinking it would reset on hitting the "+" sign next to it. OK, that's fine now I know how it works. You'll need to advertise that feature because it's not obvious.
It will reset only when that forum is not expanding at startup as defined in Account setup, Forums.
As I said, the reset on the + sign is not done yet. We are releasing it as is before going too far and see it that is the best approach. If yes, we would announce it later.
