Creating a Large Scale Session
By default, Collaborate sessions support up to 250 attendees. You can now create a ‘Large scale session’ to allow up to 500 attendees to enter.
When creating your Blackboard Collaborate Session, select the ‘Allow 250+ attendees to join’ checkbox in the Session Settings area to generate a large scale session.
Large scale sessions have a maximum duration of 6 hours, and you are unable to create large scale sessions for repeating, or open ended sessions. New sessions must be scheduled if you need multiple large scale sessions.
During a Large Scale Session
Not all features are available within a large scale session. Participants can't share audio, video, post chat messages, or draw on whiteboards and files. However, Moderators can enable the chat room for all attendees once they enter the Collaborate session. Turn on the chat from the Session Settings area.
Moderators and Presenters can always share audio, video, create annotations and share files in large scale sessions. If you want a single participant to share audio (or video / share files etc), promote the participant to presenter.
Breakout Groups are always disabled in large scale sessions.
