They were practically begging for questions in that room. If any of the people that keep on top of this issue had been in that room, it seems like it would be so easy to ask the question. Unfortunately, it doesn't appear that there were. I wish all these things weren't so far away from where I live.
I'd have bombarded them with question - everything from class balancing (of which I know nothing) to SGRAs and chairs. Of course, I can only go as far as Brighton and apparently they don't "do" questions at their pub crawls.
