The application seems easy enough to use to book, and I like that I can record. I am familiar with the use of Z____ and was having trouble with the first use as when I went to use my powerpoint it did not seem to advance for the participants unless I was not in the actual slide show, but in the ppt development window. I think I just need to figure out how to show the powerpoint in full screen for the participants..... also the participants were unable to unmute themselves for questions at the end. I think once I nail down how it functions differently that what I am used to, it will be a really good option. Maybe a user guide somewhere is what I am missing....
