Yes. I argee also. It makes it easier with the IH's, plus, do you really want to waste PM box space by PMing someone a simple thing as "Check the IH"? Plus, if the person's PM box is full and he/she forgets..... Then what you going to do?

Social Groups, stick 1-2 people in charge of looking over them. For profiles, If someone reports something, have a Moderator check it out. That's what they there for!
