I am not a user, but stopped by to support this product. I'd have bought a Tier 1, but felt disappointed that Tier 1 is missing two things that could have been useful:
One-click sharing (audio, video, slide, document) and hide muted attendees
Customizable pop-ups & button bar

I did not need the affiliate referral stuff, but Tier 1 is obviously nerfed without access to One-click sharing and Customizable pop-ups & button bar. Can you convince me otherwise? I might still buy before we part ways!
