This page uses frames! If you're reading this, it probably means you're using a browser that doesn't support them (or you're looking at the code of this page - naughty!!). Get Microsoft Internet Explorer or Netscape Communicator.
This is for those of you who are using Lynx (a great program, in my opinion) to browse this site - I've put all the navigation in the frame called SIDE, and all the content on the frame MAIN. I realise it is a little inconvenient to navigate like this, but it was the best way I could design the site for GUI browsers.
