PCW: Can I do an audio-only chat?

Barnes: Yes, but you have to disable your camera in the hardware setting in your computer. Skype has traditionally done voice calling first and then video. But Facebook wanted the reverse. They wanted to focus on video and have that come on automatically with the voice.

PCW: What if someone tries to video chat with me but I don't feel like chatting?

Barnes: The first time a friend calls you, a window pops up asking you if you want to start the video call. But at all times after that the chat begins automatically. So if you don't want to video chat you can become invisible by tweaking your setting within the chat client in the same way you become invisible for text chat. PCW: As far I can tell, you can't say you're available to chat with one person and not another.
