An important consideration in the design of the tool, was the level of technology available to users. Some users for example, would be using older PCs, running a variety of software and possibly accessing the web via modems. It was important that users in this kind of situation could still access the tool effectively. The site was therefore designed to maximise access rather than to utilise the latest functionality of web browers.
Please send feedback if you have any comments on the design and/or usability of the site.
