Catching up

Apologies for my absence here these last few weeks. Thanks to everyone who came along to the talk at Greenwich, and to those who made the trek to Bristol. It was a most enjoyable way to spend half a day and I know everyone came away very enthused by the idea of doing something similar next year. All credit to the organisers both for making things run smoothly, and for picking such an excellent venue.

It's been a busy few weeks, for various reasons. By now word seems to be out on the street...
