Announce is a simple Macintosh utility for sending instant text and audio messages to one or more users on an AppleTalk network. Announce is basically two programs: An application program, “Announce User” (for sending messages) and a system control panel, “Announcer” (for receiving messages).
You can send the same message to a pre-saved group of users. The sender can immediately tell when the receiver has acknowledged a message. You can also log incoming messages to a text file.
Both Announce User and Announcer are designed to use very little memory.
