Tell you what. I'll get some kind of little stickers that you can put on your Festival button and give them to Beth and Mary at the "Festival Services" desk on the third floor of the Center House. If you go up to the desk and say the secret password, they'll give you a sticker.The secret password is (shh! Don't tell anybody!) "May I have a Mudcat sticker, please?"
If you see somebody else with a sticker like yours on their button, you'll know they're another Mudcatter.
