I have tried and tried to get off this list. Somehow my address has changed from the time I originally subscribed. I am on a network and our computer people can't figure out how to get me off. I've sent a message to the list owner Chadwick, only to have the message returned undeliverable. I have had a friend send a message to Chadwick, to no avail. I am going out of town for about two weeks and I can't even suspend the list for a short time. I NEED HELP. Thanks in advance for any advice. Ann Kain National Park Service [log in to unmask]
