Update Tuesday 29th Dec: All Done. Thanks for bearing with me!
I need to so some work on the database that underpins this entire site. Unfortunately I need to take the entire site off-line to do this!
As a result the website will be unavailable for a few hours tomorrow evening (Tuesday the 29th of December) while I do this work. All the sites hosted on the domain will be affected.
A lot of the downtime will be waiting for our web hosts to implement something and that is where I see the delay happening. You can keep an eye on the Twitter feed if you want as it will be running during the upgrade. If I run into any serious issues I will update the twitter feed to let you know.
