This is a bit early, but I will be offline for most of the next week, and the other meetup announcements jogged my memory. I am in the UK from North America, until August 31 - and Alnedra mentioned that she would be coming to Britain in late August for a course. London appeared to be the centralish place, though I would be okay moving around a bit (I'm based in Cambridge, but I just got back from Lincolnshire, lovely place, great sausages).
London Meetup? Back in June there was a talk of a UK meetup in the London area when certain Monkeys happened to be in the area. I think late August was mentioned. (that's London, UK, not London, Ontario, though it is a mistake easily made)
