A hidden postmaster is one that does not appear on the HELP or RELEASE messages, ie one that will probably not receive stupid questions from users. It only means that users have no way to know this person is one of your postmasters, and nothing more. A 'cc:' postmaster does not have full privileges. He can create lists, stop the server, but that's all (or nearly so). A 'quiet:' postmaster is one that doesn't receive any message from LISTSERV, unless it is a reply to a request from him or suchlike. So, what you want is probably: postmaster = 'CCMRG@BOSTONU hide: quiet: cc: OPERATOR@BOSTONU' Eric
