The primary goal of BigBlueButton is to enable remote students to have a high-quality learning experience.
After fourteen weeks of development, untold number of cups of coffee, and a lengthy testing period, the BigBlueButton Development Team is proud to announce the release of BigBlueButton 0.7.
The biggest feature in this release is definitely the integrated whiteboard.
