ROUTINE SITE MAINTENANCE 23 OCTOBER

Just to let you know that the site will be unavailable for a part of the day on  Wednesday, 23 October, for routine maintenance by the server.  If all goes according to plan it should only be for a couple of hours at most, but last time it took a lot longer than that, so please bear with us if that happens again. Sorry we can't be more precise, but it isn't in our control.  

Apologies in advance for any inconvenience.
