Players taking over for other players temporarily

[Tnarg]

I am going to be going on vacation and it has been mentioned that having other "trusted" players take over for you while absent is about the best thing one can do.

I am curious though, if this player is not in the game that you are in, it is definatly obvious that I need to withdraw from the game and the replacement needs to join the game. Am I correct in my assumption? Is there anohter way around this? Thanks.
