I was delighted to learn that DUALHDR is now available as an option. I want to make an announcement to my list about this, but I'd first like to know how subscribers can return to the normal setting if they set themselves to DUALHDR and then decide they don't want it. I was able to set one of my accounts to DUALHDR by sending listserv a SET WMST-L DUALHDR message, but when I sent a SET WMST-L NODUALHDR message, I was told that was an invalid command. Can anyone tell me what I should have said, and where I could have found that information for myself? Many thanks. Joan Korenman, WMST-L Listowner KORENMAN@UMBC Univ. of MD.
