So going with the powerpoint option, do I create it and then do a screenshare through Meetingburner?

Yes. When you start your presentation, there will be a little button at the bottom to start screenshare. Then you will have to download and run a little java code for it to start.

Then you press “start sharing” and you are live! Hit start presentation and off you go. Make sure you set it to record… or I think meeting burner records automatically.
