On the following pages the background image goes down to the bottom of the content, and then there's a large grey area below the content [certainly in Safari 3.1, Firefox 16, Chrome 22.0]:
I'd like to get rid of that whole bottom grey area.
I've viewed the pages with Firebug and the grey area doesn't appear as a margin bottom or padding for any of the divs. Looking at the box model tab it also only highlights the background-image area.
Where has this extra bit of the site come from? Any insight much appreciated!
