 * The service is hosted at I-MATH.
 * 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'.

 * 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.

= FAQ =

 * 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.
