A subject-oriented mailing list identified by a distinctive name. When a message is sent to the mailing list name on a BBS, it is automatically forwarded to all the addresses in the list. Unlike a thread, the messages are not displayed or archived. Unlike a forum, the responses are returned directly to the sender, instead of the group. Unlike a chatroom, the exchanges are not live. Listserve messaging, also known as a "reflector" or "lstsrv", is most appropriate for technical or academic communications. See instant messaging, usegroup.
