I suck…
Due to an incredibly stupid mistake on my part, I accidentally managed to `rm -Rf` the /home directory on the server this site is hosted on (and lost about 200gb of data, including everything that was hosted under the home.dataforce.org.uk domain.)
As such this site will probably be horrible broken for some time (logins won't work, changing page style, any images or downloads) until I recover the up to date version of the scripts and as many of the files as possible. (Most of the actual content for the site is stored in mysql so none of that was lost, just the php scripts that pull it all together and anything non-page like).
If you came here looking for something that now gives you a 404, feel free to leave a comment here and I'll see if I can find what you were looking for.
