Abstract: A system and method for improving event and user communications and experiences. (e.g., managing meetings and their participants) is disclosed. By treating events such as meetings and their participants (meeting leaders and invited attendees) as a managed system, the present invention improves the quality and outcomes of meetings and the satisfaction of the participants. The present invention also makes joining of this intelligently-managed system particularly simple for new as well as returning participants, by providing a unique approach to the issues at the pre-meeting, meeting, and post-meeting phases in order to generate scores for the particular meeting, each participant (meeting leader and attendees), and a meeting graph linking the performance of each participant (meeting leader and attendees). This score is used to adjust and predict participant (meeting leader and attendees) behavior in subsequent meetings.
