Hit the MM mark this past week... what do they send you?

And would you go through the trouble to have your existing reservations updated to show the MM status? I am thinking yes, because recently a GA explained to me that my chances for an upgrade were being trumped by a PM/MM and I was only a PM. So it would seem that MM status might elevate one above other PMs... but then I still don't get the upgrade heirarchy yet anyway!
