The TinyChat web site sums it up this way:
“Tinychat delivers dead simple video conferences without the extraneous ad-ons and inconvenience, making video conferencing an accessible, uncomplicated experience. It works on Windows, Mac and Linux; with Firefox, IE, Safari, and Chrome; and there is a version available for iPhones. You can have up to twelve people in a room with HQ video (200 via chat only), protected by passwords and moderators, share your desktop with them, and your conferences can be recorded and embedded on your website. But the best news is this — we can provide all of these awesome features in a package that is attractive, streamlined, and easy to understand. Tinychat is the ultimate meeting solution for those who want to meet without stress and hassle.”
If you have a webcam, you will want to try online videoconferencing using TinyChat. Simply go to the TinyChat website, enter a name for your chat room, click on the "Create your room" button:
You then will view a screen that includes the URL of your video "chatroom":
You can simply send the URL to anyone that you want to videoconference with - copy the URL and mail it out. Then click on the "OK, I'm read to join my chat" button.
You then will be in your chatroom. Click on the "Start Broadcasting" link to activate your video and audio. As others join your chatroom, you will view their video:
Feel free to invite any of the workshop participants to a videoconference using TinyChat.
