I am really sorry @madams - I had not seen my notifications for the forum. I actually wonder if I still get them as we have changed forum. Anyway… thank you for pointing out the issue with the video tagging application. I worked on it and re-launched it but it is still not working - the reason is that when the link of a video that was uploaded by a user infringing copyright appears it might be that it is no more visible because YouTube has removed it. I will ask @MKrz17 if she has time to work on the code to fix it next week.
Meanwhile, many thanks again and Happy New Year!
