I agree with TG, a pattern would be nice. As far as disappearing, if I disappeared, I would probably be deceased. Not that I plan on dying anytime soon, my husband or anyone for that matter wouldn't know to contact anyone from the boom. I do think I have listed my home phone, which we currently still have, but if we didn't, my husband wouldn't check my phone for messages. He has a flip phone and doesn't even text.
Maybe we should list a secondary contact number in case of emergency. I would list my dd phone number or one of my sisters which both know and understand my connection to the Quilting Board and Boom swaps.
