We use a list exit to prevent subscriber sign-off. The exit is currently in use on LISTSERV 1.8e; it was previously used on LISTSERV 1.8d. I have not personally tested it on more recent versions of LISTSERV. If you would like a copy of our code, please contact me directly. All the usual caveats apply. -- Paul Russell, Senior Systems Administrator OIT Messaging Services Team University of Notre Dame [log in to unmask]
