From today, when logging into the game, you will notice that the Welcome Screen has been replaced with what we’re calling the RuneScape Lobby.
There are several things you can do in the lobby before you enter the game. You can see which worlds your friends are playing on; you can chat to friends or enter a Clan Chat; you can switch worlds and set your favourites; and you can change your display options. The lobby adds no additional clicks to getting into the game.
When logging out of the game, you will re-enter the lobby and stay logged in for up to an hour (though you can fully log out by clicking on the ‘X’ at the top-right of the lobby). As you don't need to enter your password to go from the lobby into the game, this should make things much more convenient when you want to change worlds or take a short break.
