BBoard is a web based discussion system for the ArsDigita Community System. Once installed and mounted, bboard instances provide locations on the site that contain discussion forums (e.g. http://developer.arsdigita.com/bboard/). Users can post and read messages within individual forums, which are generally geared towards specific topics or audiences. This basic functionality is supplemented with a variety of additional features including image and file message attachments, email notification, categorization, and moderation facilities.
