There are six groups.  Here is what they do.

VI Player (Alive) - Town Player, still on the Island.  Can post in the main game thread. Can't see the Afterlife, Mafia, or Spec Thread.
VI Player (Dead) - Town Player in Afterlife.  Cannot post in the main game thread. Can see and post in Afterlife. Cannot see the Mafia or Spec Thread.

VI Mafia (Alive) - Scum Player, Still on the Island.  Can post in the main game thread.  Can see and post in the mafia thread.  Cannot see Afterlife or the Spec thread.
VI Mafia (Dead) - Scum Player in Afterlife.  Cannot post in the main game thread.  Can see and post in the Afterlife thread AND the mafia thread.  

VI Spectator - Can see and post in the spec thread. Can see the mafia thread, but cannot post there. Cannot post in main game or Afterlife threads.

VI Shaman - Assigned to Roy. Can see and post in both the main game board and in the Afterlife board.


When a Player dies on the Island, you simply remove them from the Alive Group and add them to the Dead group.

When a Player dies in Afterlife, just remove them from the Dead group and add them to the Spectator group.
