Have you considered making that individual a silent listserv maintainer? If you are going through the exercise of changing a list-owner, you should consider making the list-owner a (new superowner) list with that individual(s) subscriber and/or owner of that new list. That new list then is referenced in the old lists as: OWNER= (new_list) Other scenarioes can also be envision e.g., use of the Insert Keywords (.IK). /Pete On 3/9/2010 5:42 AM, subramanyeswari wrote: > Hi, > > I have nearly 1000 lists.

Is there anyway which i can do this for all my lists in a single way with a command? > > Thanks > > >
