Well, it should be obvious (I hope) - the site has had yet another upgrade. Let us know how you like the new theme (if it doesn't seem to display correctly for you, try a force-reload in your browser, e.g. by holding down the shift key while clicking on the reload button).
I will now try to spend a bit more time on the actual content of the site than on the software that runs it. So stay tuned for some new stories in the not too-distant future ...
