Question for techies... How would VERB test how ma

Question for techies... How would VERB test how many people can watch a live webinar.. I had seen a post a week or so ago showing the maximum number of viewers other vendors had and was wondering if VERB technology would allow more etc.. I also thought this product would be good for churches who do online worship.. They could have a clickable offering for those who wanted to donate, show the text for songs by a simple click or even bible verses etc...https://www.lakewoodchurch.com/watch-online
