ChatNet provides the simplest Macintosh interface to chat and send files on the Internet or a Local Area Network. ChatNet offers two modes for chat. The AppleTalk Mode allows multiple Macintosh computers running ChatNet to chat or send files on a Local Area Network, with or without a Server. The IRC Mode allows chat and file transfer through an Internet Relay Chat Server. ChatNet acts as a client program providing a button oriented graphical interface for all IRC functions. There is no need to know any IRC commands.
