A communication session, facilitated by means of a computer network, between several participants, each of them having access to all messages submitted. Note: Messages, in general, have no specified recipient, but are sent to the entire membership. Messages may contain text, video, audio, graphics, software, or a combination thereof. Some of these may be contained in the message and may be stored on line for future retrieval. Computer conferencing can be conducted either in real time or in store-and-forward mode.
