Each link on the contents page will start a new web browser window. In most cases, each sketch provides you with a guided tour and a link you can click on to send us feedback.
You will need a frames-capable browser (a recent version of Netscape or Internet Explorer) in order to see the tour and comments that I have wrapped around simulations of the proposed interfaces. Because I have added this additional material to what the NetLearn user would normally see, it was sometimes necessary to use more screen space than we would expect users of NetLearn to have. Hence, the sketches will usually be easier to view with a large monitor set higher than 800x600 resolution.
