OK recent changes have begun introducing HTML5 into the site. This should make for a better viewing experience for everyone using a modern browser like IE10 (or IE9 for XP folks), Chrome or Firefox.
This site has (at one point or other) had all it’s pages validated against the W3C’s HTML4 validator. All pages that have actually been validated as HTML 4.0 (Strict or Transitional) have this logo shown at the document footer. Any pages that failed will not, but should at least be well formatted HTML, and should be soon be corrected!
If you are experiencing problems using this site, or believe you have spotted an error then please mail the webmaster with the details and we will endeavour to correct the problem.
