I did ask people to confirm by Wednesday (4 Jan.), but that seems to have got lost somewhere. I'll reiterate. Confirm attendance by leaving a comment or forum post saying "I'm going" or "I'm not going" and also leave some sort of identifier (in these comments) so I can create a register. I'll be in Cheshire most of the day, so the deadline is really Thursday, whenever I get up, but shhhh.
