Recently, we have noticed that the site is starting to struggle a bit with the amount of traffic it is starting to get. There are times, currently, when the site slows down and does not react in a timely manner. We are therefore investing in a series of upgrades to the server.
Unfortunately, our hosts can only say that this will take place within the next couple of weeks - when we hear more, we will give you advance warning.
During the upgrade there is the likelihood that the site will not be accessible for a few hours whilst the changes are being made. We are sorry for any inconvenience this may cause, but we hope that we all will see a marked improvement in the usability of the site.
Here's to the future! :-)
