I've done a little bit of tidying up on the site, removing old styles that nobody used (or at least, nobody should have been using), and various commented-out bits of HTML that were just using up bandwidth.
I've also taken this opportunity to set the default style back to the blue one. There's a fundamental problem with the 'recycle' style under IE. Also, quite a few people didn't like it (especially the fuzzy way of highlighting URLs). Kate and I liked it
