I'm not sure if you know but it only became known on the Thursday that the study was coming out on the Friday. We did have a general idea it was coming but it had been expected since around October. I read all the manuals that had been leaked, both out of general interest and also to help understand it, but I'm not sure I would have paid anyone to do that. Also I read them in October/November and have forgotten a lot of them! I find it an interesting question as to who should write in. Unless one allocates CEO(s)/similar quite a bit of time to follow the literature and discuss points with others, their letters may not get at a lot of issues. And normally any one letter can only touch on a small number of points which is why I've come to conclude we need as many people as possible writing in.
