CJAFChatting

Here is the first version on the tiny chatting app 'CJAFChatting'. It listens on port 4546, so be sure to port forward port 4546. It is also compatible with Hamachi, so you don't need to portforward.
The zip file comes with two apps:
The CJAFClient and CJAFServer.
The CJAFServer runs and listens on port 4546 for a client to make a connection. The CJAFClient attempts to connect to the IP that you give it at startup, and if the connection is successful, the Server and client may choose a username and start chatting!
The Server has a feature that also listens for certain messages. If the Client says 'Ping!', the Server responds with 'Pong!', but only the client can see the 'Pong!' message.
