Described is a method for retracting an instant message from a receiver in
an instant messaging session. A request is made to retract the instant
message from the receiver. If the receiver is present in the session, the
instant message is removed from the user interface of the receiver.
Notification is sent to the requestor to indicate whether the instant
message was successfully retracted and whether the instant message was
saved by the receiver. Optionally, the method allows an entry made in an
instant messaging log to be retracted when the corresponding instant
message is retracted.
