As long as our Y27 uplink is not saturated, we can create additional instances - we should not have performance problems.
The sound seems to be quite well.
BigBlueButton seems to be a 90% replacement of Adobe Connect, plus 'Break Out Rooms'.

Best Practice: Speaker

Create a meeting room. One per lecture and/or per exercise. Room might persist over the whole semester.

Publish the URL (on the lecture homepage, per email to the students).
- There is no group permission - anyone who knows the meeting room URL might attend.

After every login: As speaker, always select microphone. Start a short audio test - you should hear youself as echo.

How many people watched the recording?
- Currently we do not have any statistics (#10353, #10354) - we're looking to implement a statistic.
How does the students find the recordings?
- Conferences started via w3/my: The recordings will be listed on the homepage automatically.
- Conferences started individually: The lecturer/tutor has to publish the 'room' link. It's the same link as the students use to join the conference.
How to save the chat
- Menu (three vertical dots), in chat windows, upper right corner: save
- The chat content is gone after closing the meeting.
How to export the annotations of the whiteboard
- Currently: not possible (#10352). We're looking for solution.
