I will make MM on a trip to Venice in three weeks. I noticed in the Delta response it said you would get new credentials in a few weeks. Does that mean something I don't have to print off on my home printer (as I had to do when I descended to the realm of Silver)?

Also for the person who was surprised anyone but a Diamond could make MM, I have never been a Diamond, though I was a Platinum for about 10 years. For me it's because I only fly internationally.
