Suitable Browsers We tailor the Web page to the Browser		For this experimental Website our pages adapt automatically to the Browser in use. We cover most major Browsers (for details of those we support and why, see Version details).
Our demonstrations all require JavaScript		We created this Website to show how a blend of JavaScript and careful writing can turn a Browser into a patient, Personal Tutor. Without JavaScript, these ideas can't be demonstrated.
Browsers are free		The point of Browsers for interactive content (such as Corporate Training Courses similar to our demonstrations) is they are free. No licences to buy, however many machines you have.
