I realise I'm way too late to be included, but happy to be the 3rd or 4th reserve. Maybe if individual participants don't post in the first couple of weeks in row, they can be replaced by a reserve.
Sorry PJ, I have been really busy of late. Can still go in a team if there is still a place or can go reserve if I am too late. I'm a Cantab, but can see you already done lots of work on putting teams together, so easy with any team.
