BigBlueButton ============= 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 LibreOffice), webcams, whiteboard, chat, voice over IP (using FreeSWITCH), and desktop. It can record and playback all content shared in a session. The use cases for BigBlueButton are * One-to-one on-line tutoring * Small group collaboration * On-line classes (50 or less) For more information on the latest release -- including installation instructions, demo server, API, and overview of architecture -- see [http://docs.bigbluebutton.org/](http://docs.bigbluebutton.org/).
