Actually I understood that if the mods made a decision you didn't like, you could PM them about it. Usually if you just say that you want to add foo because bar they'll accommodate you somehow. I can't shake the feeling that we've let instances pile up before making this thread.
I've watched mods split threads before but that was usually because two topics were going on at once and not because Alice and Bob wanted to fight. Usually no one even complains as long as Alice and Bob are right some of the time.
