it is very important that we do not lose the list

Instead of having an "A" list for invitees ("B" list, etc.) I've decided to structure it like Major League Baseball. People who have to be invited are on the "Majors" list. People who I'd like to invite, but can be cut if completely necessary are "Triple-A." People I don't want to invite but might have to are "Double-A." And people who are really bad at baseball (and won't be coming to my wedding) are Casey Blake.
