BigBlueButton is an open source web conferencing system for on-line learning. We believe that every student with a web browser should have access to a high-quality on-line learning experience. We intend to make that possible with BigBlueButton.

BigBlueButton supports real-time sharing of slides (PDF and any document readable by OpenOffice), webcams, whiteboard, chat, voice over IP (using FreeSWITCH), and desktop. It can record and playback all content shared in a session. The BigBlueButton project is is supported by a [community of developers] (http://www.bigbluebutton.org/support/) that care about good design and a streamlined user experience.

The use cases for BigBlueButton are

• One-to-one on-line tutoring
• Small group collaboration
• On-line classes (25 or less)

BigBlueButton is built on the [shoulders of giants] (http://www.bigbluebutton.org/components/).

All the core information is at the [Google Code project page] (http://code.google.com/p/bigbluebutton/). Here are a few quick links
