I've just been trying to help someone who is delivering GoToTraining sessions for up to 200 people. They are using breakout rooms to facilitate 'smaller' discussions and they need to move people around the breakout rooms, but they are so big that they are unable to see all the attendees in each room. They also find that they lose people - on one session, only 140 people made it into the breakouts. Is there a maximum limit on the numbers? Is there any way you can expand the list of people in each room?
