Abstract: A method and apparatus for controlling participant input in a conferencing environment supporting at least first and second end points which can operate in at least two different modes. While in the first operating mode, the end points can make changes to the conference data at will. The conference remains in the first operating mode until a request is received from a participant to change the conference to a second operating mode. Once this request is received, the conference switches to the second operating mode. While in the second operating mode, only one of the first and second end points can make changes at any particular time.
