FrankTrollman said:It isn't even "in-character" because it's a private message to the person outside the game.

As an important aside, that claim is definitely unfair. "In-game" messages take a full turn to get anywhere, and are therefore useless for in-game diplomacy. PMs are the only viable option, unless email addresses have been publicized.

Generally, I think the "Royal We" and the content of one's signature tend to show quite clearly when a message is meant "in character."
