In addition to allowing persons in the room to enter the queue by “raising their hands”, you may enable automatic queuing, where each person entering the room is given a place in the queue in the order that they arrived. For situations where you want to control who can talk in the room, you can set the room so that only the room moderators and the person at the top of the queue are able to talk to the room. VideoCafe’s room privacy feature can also be used in conjunction with queuing if you do not want the persons in the queue to be able to see each other’s video while waiting.
