I am in the process of moving this site to a new server. This should address the issues that some people have reported when trying to access the site.
There will unfortunately be some downtime whilst the changes are propagated. If you are reading this, it will mean that these changes have already been propagated to your service provider.
The transfer to the new server has now been completed. It appears that the changes have propagated, so everything should now be back to normal.
If anybody still encounters problems accessing this site, please let me know.
