> You probably want to do this QUIETly... > > QUIET SET listname NOCONCEAL FOR *@* On the other hand, you probably want to ask subscribers why they're SET to CONCEAL. If you UNconceal them without asking them first, or at the least, without giving them the opportunity to UNSUBSCRIBE first (so their presence on the list in not revealed), you'll likely create some serious animosity among subscribers. To reSET them to NOCONCEAL "QUIET"ly would be even more egregious than simply doing it without asking them first. (Maybe you've already done all this "checking". If so, my advice can be ignored.)
