Not a major upgrade but I have tidied up the code and made the site HTML5 compatible. I am not sure if this adds anything or has any advantage but it keeps my coding brain working! A few CSS terms have become obsolete but nothing major the most difficult bit was getting the site map table to validate at W3S.
I have also altered the menus slightly so that they work better on Android tablets, iPads and probably phones. They now stay open if you tap them, the items are perhaps a bit close for large fingers but the extra space at the top prevents most of the auto triggering.
