With a simple and straightforward method of using, Facebook video calling is simply awesome. To get up and going with using the video feature you first need to install a plugin (http://www.facebook.com/videocalling) and from that point on you have what is necessary to use this new feature.
Making a video call is easy.
Look at the list of your friends (in the lower right-hand corner of your Facebook page) who are currently available on Facebook chat. Double-click a name, and you’ll see there’s a new icon at the top of the chat screen — a small video camera. Click it to send an invitation for that person to participate in a video chat. They’ll receive a pop-up notification to a video chat, and if they don’t have the plugin installed, they’ll be prompted to install it.
The video and sound quality is exceptional; however I do have my problems with the video chat screen taking up your screen and the inability to resize it. All in all, I like it. Good Job Facebook Team
