Whilst I can see the merit of supplying the questions in advance to Mr Hopwood, would it be possible to also publish the questions in advance in this thread ?
Sorry, but at this late stage changing the plans in not an option.
Questioners know what they have asked, and will already have corollary views that they'll be able to come back with quickly once they see Mark's comments. We've been running as a forum for a dozen years and it's pretty unlikely that much unexpected/new will be asked.
I would worry that publishing the questions in advance would lead to a significant number of people preparing their own follow ups / corollaries to paste in very quickly once a thread was started, and that would change the metrics of the whole system. Rather like a dam of comment on the same issue breaking. That is why it is set up with controlled release.
Undoubtedly, we will ask ourselves "how did that go" to learn for the future. But - for tonight - the planned metrics remain on plan.
