Just to let you know I've updated the site to one of the new Blogger Templates this morning. I've tried to keep the 'look' and 'feel' as close to the old format as possible.
The main advantage is the additional width to the page. You should be ok viewing in any resolution greater than 1024 pixels. The extra width in the body of the page will mean that when ever we include photos in a post the text will not look quite so cramped.
Any problems please add a comment and I will see what can be done.
