Mute is a four letter word.
Tried using Google+ Hangout this evening. Not my first time using it, and I've very much liked its performance the times that I've tried it before. This evening, however, the person I was trying to talk to couldn't get the mic to work. We spent about 30 minutes trying to get things working, but no dice. To add insult to injury, however, when reporting the problem, there was no way to say what the problem WAS - just several checkboxes, none of which fit his scenario.
