Hi Birgitte,
Yes, you did raise your hand, but I unmuted everyone so that they could ask questions. That may not have been the best thing for me to do given the number of people doing the lecture. One of the reasons I did it this way was that Weiqing was having difficulty with the hand-raising and I was a little afraid that others might be having the same problem.
I did get your question, the one that got typed in the question box. To answer it now, I did record this session and will post Paul's presentation and the recording of it to the website. I have a minor issue, though. Because of the technical difficulties we had, the recording is a whopping 125 MB which is too big to accommodate on the website. I'll try this afternoon to cut it down to the maximum 100 MB for the website so that I can upload it. Failing that, I may have to put it on my personal website for download.
You will be able to go through the recordings and pause them, fast-forward through them, etc.
