<strong>Game Related:</strong>I agree with Jack.  Part of the planning and communication will depend upon how each character knows each other character and what individualized histories they have.  While the group likely did a lot together, they didn't do everything, and whose to say what happened between two characters after dropping off so-and-so besides the players of those two characters.  That's what communication is for and when we get the relationship thread up that'll be key details to put in after discussing them with the other players.
