Abstract: Computer-readable media embodying instructions executable by a computer to perform functions having corresponding methods comprise: joining a user of the computer to an electronic meeting; causing a display device to display a list of participants in the electronic meeting; receiving electronic messages, wherein each electronic message comprises a comment contributed by one of the participants; and causing the display device to display each comment without displaying an identity of the participant who contributed the comment.

Abstract: A communication device having corresponding computer-readable media comprises: a receiver configured to receive, into the communication device, i) audio transmitted by a headset, ii) a voice activity notification, where the voice activity notification indicates the headset is detecting voice activity in the audio, iii) a mute status notification, where the mute status notification indicates whether a first muter in the headset is configured to block or pass the audio; a second muter configured to pass or block the audio; and a notifier configured to provide a user-perceivable notification responsive to contemporaneous occurrence of i) the headset detecting the voice activity, and ii) one or both of the first and second muters being configured to block the audio; where the user-perceivable notification indicates which of the first and second muters are configured to block the audio.

Abstract: Apparatus having corresponding methods and computer-readable media comprise: a muter configured to pass or block an audio signal; a voice activity detector configured to detect voice activity in the audio signal; and a vibrator configured to produce a mechanical vibration responsive to the contemporaneous occurrence of i) the voice activity detector detecting the voice activity in the audio signal; and ii) the muter being configured to block the audio signal.
