I have not received my fan club package since I just joined this month. I was thinking, however, that it would be neat if they would send out a passport type book, of decent quality (leatherbound, or like US passports). A place to keep your ID card, and various other things. Then, have Blank pages that can be stamped as you visit various Toy Fairs and Comic Conventions. Maybe an embossed stamp. Maybe have identification that you can even mark that you are a member of various "recognized" websites or local groups (ie 501, Chicago force, etc.) Have additional places where you can mark off your years with the fan club.
May seem dumb but I think it would be neat.
