IMC User's Manual | System Messages
What those big yellow announcements are.
System Messages are posts that are directed to all rooms, public and private, to announce something important. They have a bold yellow background and the words "IMC SYSTEM MESSAGE" at the top of the message. Do not respond to these messages. They are the equivalent of an announcement over the P.A. in a public place. Usually we use these to announce imminent system shutdowns, new rooms, problems, or other important breaking information.
