​
As a moderator, you can promote or demote other viewers’ role status in the live meeting or remove a user from the meeting.

If a user has entered as a viewer, you can promote their role to moderator or demote a user from moderator to viewer.
Rolelist
Moderators appear in the users list with a square [1] avatar icon, while viewers appear in the users list with a circular [2] avatar icon. Use cases for promoting a viewer to a moderator include:
  • Upgrading a guest speaker entering the session to the moderator role gives more control over the session to the speaker.
  • Promoting a user who was mistakenly assigned the viewer role in the LMS when the meeting was created.
Use cases for demoting a moderator include:
  • Demoting a moderator who was mistakenly assigned the role in the LMS.
  • Demoting moderators to reduce the number of users who have unlimited access to the session.

Removal persists for the duration of the session. Specifically,
  • If you remove a phone user, they are not able to dial back into the session from the same phone.
  • If you remove a regular user, they are not able to rejoin the session in a similar manner.
For example, if a student joined through the learning management system (LMS), they would be unable to rejoin the current session through the LMS. The same applies to a Personal Rooms link or Guest invite link. If you choose Prevent this user from rejoining the session, they will not be able to rejoin for the duration of the current session. mceclip0.png Again, the removal is only for the current session. A removed user can still join other BigBlueButton sessions or the same session again if restarted at a later time.
