Sorry if this was asked or explained in the deal and I missed, but can you assign various roles to users with different access or capabilities?... like say I'd be on control of the webinar mechanics and I assigned a moderator, 2 or more speakers, and then a plethora of attendees. The moderator would have nearly the access that I have, speakers ability to speak when selected, and the attendees/viewers can chat and raise their hand to ask questions of the speakers.
