I have a mailing list running 1.8c in which I have set: * Subscription= Open,Confirm * Validate= No Some subcriberss have mentioned to me that they need to use the OK confirmation mechanism when they issue SET commands for the mailing list. This is surprising to me, because I don't understand how this feature started to occur and how it's specified in the list header. In fact, I can't duplicate this feature when I subscribe. While LISTSERV does request the confirmation when I subscribe, it allows SET commands without requiring it. Yet a user showed me a message they received proving that it did occur when they did a SET TOPICS command. Any idea what is going on? Thanks. Mark
