With GoToMeeting, you can join a meeting by clicking on a link in an e-mail or by clicking the GoToMeeting icon and entering a ID for the meeting. Users can also connect to the audio through the internet using a phone's microphone and speakers. A mute control allows you to cut the microphone when there is too much background noise at your location and by pinching the screen, you can zoom in on meeting content by up to 200%. Not only will you be able to see a list of those attending the meeting while also being able to change the orientation of the screen using the phone's accelerometer.
