We're on a somewhat dodgy server at the moment, I'm afraid -
Server Issues - but the problem should be rectified very soon.
I was offered the chance to move the site earlier, but as the hosting company are in the process of physically relocating all of their servers, I thought it safest to go with the flow, and be moved under the most optimum of conditions.
I'm expecting to have proper details this Friday/Saturday of the move - I'll keep you informed.
