You know the biggest disadvantage is that the player's login message comes into the chat BEFORE the player is authorized. (I already talked about this in another issue.) The new player has not yet entered a password (maybe it was hacker?), but everyone thinks that he has already entered to the server and begin to talk with him.

Next day the other players ask him «Hey, why did you not answer when you entered?». And he answers: «Wow, I did not have a computer at all yesterday!». So the players have a lack of trust in the server security.

I am convinced that messages about the entry of an unauthorized player should come to the console only. And when he was logged in - then in the chat.
