I like the idea of some sort of icon to show affiliation with Armorama, but with a Missing Links Nametag and a hyperscale pin, and a WWII Modelmaker propeller beanie..we'll all be looking pretty silly. Not that a bunch of generally overweight white, middle-aged, guys running out of breath into and out of the vendor room isn't a silly sight to start with
How about a sticker to go onto the nametag of whatever other group you belong to?
This way it's there with your name, and still shows membership in Armorama.
