The website is currently undergoing some essential maintenance.
Progress update: the main infrastructure work on the server is now complete, and the website should once again be fully operational. We are now accepting member registrations again.
Some less major work still needs to take place, and so the site may continue to be unavailable for short periods over the next few days. We apologise in advance for any inconvenience that this may cause.
This work is required to bring you improved security when accessing the members' area of the website. If you have any questions, please contact the Webmaster.
Thank you for your patience.
