I know, I know, back I come, tail between my legs... My excuse this time is that I moved house, and to some extent we're still unpacking. Even prior to that I ought to have written up my adventures last November teaching Dickensian descriptive writing in Argentina - or at least linked to this essay of mine like so, which gives my more or less complete thoughts on the matter.
My sponsor was the British Council, with whom I very much hope to work again in future, and they've graciously added me to their directory of UK writers here.
