Sorry. Someone at Plusnet apparently farted and blew away the disks this site was stored on, or something.
I think the database still exists and the PHP is safe and sound on my Linux computer, but the question is, can I be bothered to re-upload the site? Considering the amount of effort I put into updating it on a regular basis, I reckon no, at least for the moment. Sorry!
If you’re really good, you might get a rejigged site in the distant future. However, this would involve thinking up something interesting and low-maintenance to stick up on it, which is the difficult part.
