I installed TOPICs in my list header and today discovered that some of my subscribers were set to topics=none, some to topics=all and some to the designated topics. It is highly unlikely people would have set topics for themselves, as I've never announced it as an option and as TOPICs use on the list is very much in an experimental phase. How could it happen that listserv would set the topics by itself like this? I reset everyone to topics=all, and then reset those who'd been on nomail to nomail and those who'd been on digests to digests. Not being very adept in the programming sphere, it left me with a queasy feeling. How do I avoid listserv playing this trick on me again? Jeff
