Join a game through a friend by (an available after 3 day wait) proxy

Each player has a proxy item set by default to no one. If you click it, you can scroll through the players until you designate that your friend controls it. Use the mechanism the Game uses to select someone to write to. You cannot designate your proxy for a player who has already designated his proxy for you.

The player you designated has a second proxy item appear showing he controls your proxy.

At that point, when your friend joins a game, he can also use your proxy to select a nation for you to join. No more corresponding back and forth to try and join a game at the same time.

Once used by your friend, you are in the game just as if you had joined it yourself. Also, the proxy item defaults back to being designated to no one. You must wait three days before you can click it and designate the next player who controls it for you.

At any point, you can click it and remove a designated player, and change it to another player. The three day waiting period only applies after a friend has used it to put you into a game.
