Having a co-host when run a Zoom meeting or webinar can really help manage the call and the participants. This is useful for breakout rooms and also recording for example.
The question often asked about co-hosts is “how many co-hosts can you have?” The answer is as many as you like. Obviously no more than how many people are on the call though.
The co-host, however, can’t do the following:
-Make a participant a co-host
-End the meeting for all participants
-Start closed captioning
-Start live streaming
-Start the waiting room
Below is a video I made showing you how to assign co-hosts
