Lists can get locked automatically for any number of reasons, such as "get"ting the list and not using "nol." And LISTSERV can do it if it thinks it sees a problem of some sort which might be detrimental to the list, just as it can set your list to "hold" if there is a problem. Whatever, to unlock your list you simply send: UNLOCK listname pw=xxxxxxxx to your LISTSERV host site. The password may or may not be needed, depending on how you have such things arranged.
