Re: NNI congestion, JPs liked to call it "shuushuu"; it's the sound effect the game makes when you press confirm talking to an NPC, the NNI gate would make the sound effect but it wouldn't detarget+give you the prompt if the area was congested so you could press X over and over and get the sound effect continuously. I wasn't sure if this was due to the instance areas being full or if it was just the game screwing up because of too many people at the gate, but I'm guessing the former. In other cases you might get the prompt, press OK but then freeze up for like a minute before it didn't allow you in though.
When MMM came around at least they added the hands of darkness message, but I never quite got why they put that message instead of just "the server is full asshole".
