So in light of what you said in your previous post, does the vigilante indeed have to pm Skoolbus every night? I assumed only the night (s)he's kills, which is why I wrote what I wrote. On the other hand, in the previous game I had to send a message saying I would not be witnessing that first night when I wasn't witnessing you killing Sint, it might be similar for the vigilante having to say (s)he's not killing that night.
On another note, you said six or seven people have to pm Skoolbus each night. That would be: cop, doctor, crooked detective, mafia, (assuming I was wrong earlier) vigilante, I only count five then, unless the masons have to show their conversation to Skoolbus (just to make things more interesting for Skoolbus). I hope I'm not forgetting any roles, I counted the mafia as one person in the above since one should be enough to communicate their murderous intent to Skoolbus.
