It doesn’t get much hotter than the EGG cookin’ in July! Make sure to keep yourself hydrated with a bit of whatever you’re using for the Beer Can Chicken. Ice Cream Sandwiches are also a great way to stay cool. Looking for some great ideas for a summer cook out? Try out a Pimento Cheeseburger or Dr. BBQ’s Spare Rib Surprise. Just don’t be surprised if your neighbors stop by for a quick bite when they smell what you’re cooking!

Got it-here's a link that will show you how to align the DFMT so it doesn't move when you open the dome: http://www.nakedwhiz.com/ceramicfaq.htm (see # 47). BTW this site is a wealth of ceramic cooking info and much, much more. Give it a good look sometime. Chances are an answer to your question is in there someplace.
Venting is a good thing- No idea about your "use by date" info but I have not experienced that phenomena even with chain grocery (Kroger) foods. Wish I could offer more-will the store take it back and exchange ?
