stephtbest:

 

    There are room-defaultpolicy,role-policy,user-policy

 

    If a user or it's role have not set the policy , the room-defaultpolicy would be used .

 

    So , If you change the room-policy to 'CantGetIn' , any one can't join the room , until you set the user-policy to other value .
