Depending on your situation, either the Maestro option presented by Francoise or a List Exit. For the exit, review the Advanced Topics manual, it isn't covered in the other manuals. A list exit is not very complicated. If your LISTSERV system is going to be on a Windows platform, for example, what you want can be done with just a Windows command language batch file. >>> [log in to unmask] 4/18/2007 10:53:54 AM >>> Hey all, I was wondering if there is a way to keep someone from signing off of a list? We are migrating our lists to listserv, and some of our lists are just distribution lists for employees and we would like those lists to only have additions (which is easy) and deletions of addresses done by the owners. I looked through the documentation and didn't really see a way to do this, so I thought I'd ask the fine people on this list. Thanks, Bob
