Contact! Communication is fully operational, and now that I can easily test with 2+ clients (thanks wayne), debugging the exceptions related to game actions shouldn't take too long.
Lobbies are working with multiple clients, incuding turn yielding and starting a game. The other client gets the message, but then exceptions.
Private chat is working!
Commands are now case-insensitive, no more camelCase
Known bug: If you are in a lobby, and someone in global says something, you'll see that they sent something but won't see what it was.
