Abstract: A communication system for communication sessions, such as voice calls, conference calls, and instant messaging chat sessions, includes a plurality of communication devices and one or more servers configured to provide data communication among the plurality of communication devices. Data contexts having chronological user-generated content are established and maintained between different communication devices. An indication of current user-generated content of a data context is sent from a calling/initiating party to one or more receiving parties when a communication session is initiated. The indication of current user-generated content can then be used by the one or more receiving parties to determine whether the communication session is to be accepted and, if accepted, to quickly become familiar with the subject of the communication session.
