CritLink Mediator is a web annotation system developed by Ka-Ping Yee. This system is freely available for use on the WWW. Annotations are stored and saved in an annotation server at http://crit.org. Any page that you wish to see the annotations for must be typed into the mediator URL box. This box appears like any other form box in the top left hand page of every page while you are using the mediator. The mediator then loads the page and adds in any annotations stored in the annotation server
