By default, Collaborate sessions support up to 250 attendees. However, you can set up a session to support up to 500 attendees. Effective WT2021, supersized sessions can support up to 1,000 participants. All supersized sessions are limited:
- Webinar sessions can't be longer than 24 hours in length
- Guests must be assigned the participant role
- Participant permissions are turned off (see Using a large session)
- Breakout groups aren't available
- Create or edit a new session. See → How can I create a custom session in Blackboard Collaborate?
Set a start date and time for the session.If you don't see the large session option, check the session length. The session needs an end time and can't be more than 24 hours in length.
- Save the session.
- Click the gear icon to select the Session Settings tab.
- Scroll down to the end of the Session Settings.
- Check the box for Allow 250+ attendees to join.
- Save the session again.
Using a large session
Some of Collaborate features can be disruptive in a session with many attendees in a session so Blackboard has disabled:
- Some participant permissions:
- Share audio
- Share video
- Post chat messages – Moderators can choose to turn chat on DURING a session.
- Draw on whiteboards and files
The permissions are off for participants only. Moderators and presenters can still do all of these things.TIP: If you want a single participant to share audio or video, post chat messages, or draw on whiteboards and files, promote the participant to presenter.
- REMEMBER: Breakout groups are also disabled as the session is too large for small group collaboration.
- If you need to use breakout groups, you must either have a smaller session (under 250 participants) or set up additional Collaborate sessions and post those links in your session.
