I'd give this 0 stars if I could. Disappointing, unprofessional, unethical handling of this webinar. No reason was given for the speaker's absence, no rescheduling mentioned whatsoever. The host, I didn't catch her name, was clearly uninterested in what she was doing and in being there; she was hurriedly reading her script and by the end of the quiz (which, by the way was completely pointless; why were we being quizzed with questions clearly covering the webinar's content which didn't happen? We were all guessing and whoever got all the answers correct was either extremely knowledgeable or extremely lucky, perhaps both) we could all see her ducking her head, probably scrolling down her phone. What a solid waste of my time.
