Blindside Networks has developed a BigBlueButton Extension for Joomla, which is an open source content management system.
The extension, which can be found here, uses the BigBlueButton API to enable Joomla administrators to create and manage on-line meetings rooms to interact with their readers. Using the extension, the administrator can create, join, end and delete meetings, while readers can join meetings through a module located on the frontpage.
We now have BigBlueButton support for both WordPress and Joomla.
