How Moderated Room Works:
There is a speaker, moderator and regular user. Each role or user type can have multiple users logged in at the same time. So you could have multiple moderators and multiple speakers as well as multiple regular users.
Whenever speaker says something everybody see it right away.
Whenever moderator says something everybody see it right away.
Whenever regular user says something, the message first goes to moderator for approval and nobody but moderator(s) see it first. Speaker does not see those messages.
If moderator approves a message from a regular user the everybody see it at this time and the message author is correctly indicated (it does not say that message came from moderator)
If moderator declines a message than nobody will see it and the author of the message is notified that his message has been declined.
If there are not too many users in the room and/or if you don't mind speaker to see unfiltered messages you can do without a speaker role. That is have speaker do the moderation as well.
