I believe this question has been asked and answered in this forum on more than one occasion. If an address is listed as an owner on more than approximately 50 lists, the List Management page will not offer the drop-down menu of lists owned. The LISTSERV postmaster is the de facto owner of every list on the server, so if the server has more than approximately 50 lists, an individual who logs in using a LISTSERV postmaster address will not get the drop-down list of lists owned. -- Paul Russell Senior System Administrator University of Notre Dame
