A system to monitor and report the use of communication software applications in a computing environment including an instant messaging system, that provides local users with information describing detected uses of communication software applications by remote users. The monitored communication applications may include, for example, electronic mail, voice over IP applications, on-line meetings, and other specific types of communication applications, as well as instant messaging activities. The system potentially stores specific information regarding each use of the monitored communication applications, and sends the communication application information to one or more server process that stores the information in association with a user identifier provided with the information. The stored communication application information is then broadcast by the server process to client processes that have registered with the server process to receive communication application information associated with that user identifier.
