With humblest apologies:
We moved Adam Smith, Esq. to a new hosting service last week. It will be far superior from our perspective (and hopefully from yours as well, in terms of enhanced responsiveness on the site), but suffice to say that no good deed goes unpunished.
The transition turned out to involve far more technical complications than you would think called for in a First World country, but so be it. The migration is complete.
Welcome back!
