DON'T YELL. The microphones are sensitive -- there's no need to raise your voice.

DON'T WHISPER. Everything gets amplified during a video call. (Yes, we can hear you. If you need to say something that nobody else should hear, press the MUTE button.) Heavy sighs, coughing and paper-shuffling also come through loud and clear.
