I just discovered that an item I started, a question that unfortunately appeared to have raised enough replies that it was closed, got closed after numerous posts and before I even realized a single reply had been made.
I thought you got email notifications when someone replied to your post but perhaps I mixed Brickset.com up with another site (easy to do after you get past a dozen or so). That said is there any rule, condition, FAQ or FYI that details when, why and or what causes a thread/discussion to be closed? I know some sites (i.e. news related sites) auto-close theirs after X days.
