  • Patent number: 8428561
    Abstract: A user of a telecommunications or other computing device may notify his or her contacts of an event of interest, which event may be modified by the user's contacts without requiring the permission of the originating user to do so. In this regard, an event organizing service receives an event notification request from a user of a telecommunications device (e.g., a mobile telephone), automatically identifies the user's contacts to whom the event notification is to be published, and publishes the event notification to the automatically identified contacts. A contact who receives the event notification may update the event, e.g., by modifying data describing the event, without the permission of the originating user. Accordingly, a contact who has received the event notification may modify the event (e.g., change the date/time, change the location, etc.
