As several of you have told me, the link to the video in the previous post doesn’t work. The student group pulled it down after becoming concerned that they had caused some offence. After adding some explanatory text, they’ve kindly agreed to make it available once more. So if you missed it the first time, now’s your chance. Before you post a comment, please read the comments from the previous posting.
