A network system includes a client computer that can present multimedia content
to a user and an annotation server that can transmit, to the client computer, annotations
for the multimedia content. Users can be presented with annotations generated by
other users and can create their own annotations that can be viewed by others.
Users can be notified of new annotations by an electronic mail (email) message,
can create new annotations by email messages, and can easily access a temporal
segment of multimedia content corresponding to a new annotation based on information
in email messages.
