Thanks for the responses guys, but haven't hit it yet. (The suggestions are good, thought.)
Specifically, the platform had the ability to pre-record a webinar, then schedule it. People would sign up for it, thinking it was a real LIVE presentation (but it was prerecorded). ALSO, if/when someone were to ask a question, the organizer would be pinged so that they could respond in real time.
The search goes on!
