Question, are there any rules about out of game communication? For example, I've seen in some games where you must meet in-game before you can start communicating with emails and the like.
well, guess there ain't haven't really thought about that, but guess emailing cannot be hindered nor controlled, so its allowed.
Though im not gonna use that, unless, well i DO have the email-owner on the list, But use the ingame Diplomacy

and then the game has started.

Good luck all, and lets hope this time we can get this one work.
