All attendees join a GoToTraining session on mute?

Hi,

• Attendees do not join a training session muted by default, they can mute themselves or the Organizer can mute them. 
• If the Organizer mutes an Attendee they do have the ability to unmute themselves again.
• If an Attendee mutes themselves, the Organizer has the ability to request that they unmute.

If you tend to host sessions with new Attendees who may not have taken part in an online training before, I recommend covering the etiquette of self muting unless you are called upon to speak, during the 'house keeping' at the beginning of the session.
