Raise your hand
Add a "raise your hand" option for group audio calls which notifies everybody on the call that I (or anyone person) want to speak. This is very useful during meetings. This can be useful during any conference call so at to not to interrupt a speaker in the middle and unlike a video where you can make out from a listener's expression that they might want to talk, on an audio call the only way for someone to convey their intention to speak is to wait till someone finishes their sentence but there might be multiple people who wish to speak and not everyone gets a chance and others might not even know that a particular had something to say.
I second the above idea. I want to try holding an online SKype class but it is difficult to manage who should speak and when. When someone raises their hand, it simulates the same action as someone raising their hand in a real classroom, which is useful to have in a teaching setting. Can this feature be added?
