The Social Communication part of a player application is used to send and receive text-based messages. These messages can be sent between human players only. Using the 'Compose' panel, you are able to select one or more receivers. It doesn't matter whether they are online or not. When a receiver is not online, the message is stored and shown later when this receiver is online.

After selecting the receiver(s), you are able to insert a subject and type the content of the message itself. The maximum size of the content of a message is 10000 characters. The 'Sent' tab shows the messages which you have sent during a game, the 'Received' tab shows, logically, the messages that have been sent to you.
