A winter re-design. There were quite a few small things on the site that needed dealing with and Cliff volunteered to help with bringing WordPress to heel. I have to admit I thought the grey was particularly appropriate, given the issues with winter flying in the UK. The categories and archives should be a bit more intuitive and I feel a lot more secure about the site working in various browsers/configurations since Cliff rewrote the CSS file for me.
Let me know if anything goes awry.
