Abstract: Methods and systems are provided for scheduling and hosting communication events between users and at least one host, such as a sports hero, inspirational person, or celebrity that offers a personal interaction. The platform can process the request, execute a method specified by the host (or by others) in response to the request, determine the user or users that will take place in the communication event, and host the communication event. The communication event may be free or in exchange for payment or a donation, such as to a charity. The communication event may be a one-on-one event, or one or more to many.
