Yes Dave, I think there should always be 1 Mudcatter in the room who is willing to take on these Admin responsibilities. If the person opening the room is not comfortable with this role, they can always pass onto another Mudcatter later. Also, if the current Admin leaves, someone else should take on that role.Having someone with the @ in front of their name should let us all know who to turn to if there is a problem and should also let "outsiders" know that there is someone with athority in the room.
