Thanks @Christian DeFeo
Any chance of a video for those who missed?
Here I am, waiting to see the webinar. I've been waiting since 1445. It is now 1520. WHERE IS IT?
It looks like I won't be able to attend after all. It turns out that webex can be quite broken under Linux and that your specific webex instance isn't supported on the Android app (it doesn't give a good reason, but has worked for others I've been in).
