No, nor can they find out which lists you admin. You can always check back through the archives of a list to see whether the list admin has posted to the list and identified themselves OR you can write directly to the admin address for the list if you have a question: LISTNAME-admin@rootsweb.com (replacing the generic LISTNAME with the actual list name. If an admin doesn't respond or you think something may be wrong that the admin isn't addressing you can always contact listmaster@rootsweb.com . Joan In a message dated 8/20/2012 10:23:40 A.M.
