Hi Bill: You will have to write to the various list sponsors, if you do not know who they are, just post to the lists and ask the list owners to unsubscribe your old address. Tell them your ISP changed the mailing address without prior notice. I understand it might take a few days for 'Smartlist' at Rootsweb to catch up, doesn't sound so smart. Of course you can wait till your old address gets enough bounces (number of bounces varies according to each list) and Smartlist will automatically cancel the address. I will cancel your old address on Roll-L. If you have any problems let me know and I can post a query to the listowners list for help. Good luck, Nancy
