I'm not saying LD wouldn't want to know we care, I'm just not so sure getting calls from admin is the way to go about showing it. Certainly not if he's passed away and it's his children fielding calls from total strangers. If anyone has a physical mailing address, a Best Wishes/Get Well Soon/Hope You're Alive card wouldn't be out of line, but that's where I'd stop. Just don't expect a response if he's not answering his emails in the first place.
