Sorry that, yet again, we haven’t been available for a few days. We’ll be back very soon.
LONDON, 30 March, 2018: For the second time this month we have been unable to post anything for several days. We’re sorry to have vanished without a word: the reason was another technical problem.
The good news is that it is now being fixed, and we should be publishing again as usual from early April. The glitch removed our last three posts: we’re replacing these, complete with new images and revised dates. We’re redoubling our efforts to try to ensure that interruptions like this don’t happen. Thank you for your patience.
