I have never experienced a problem with not leaving the subject category empty. In fact, I send most of my commands by simply replying to LISTSERV(R) :-) error messages, subject and all. This has never so far caused a problem, and I do it at least a dozen times a day. That's some six thousand instances since I started list-owning. Please, don't refer to your list as "a listserv"! You run/own/manage a list. LISTSERV(R) is the program that makes the list possible; Lists can be generated by other mail distribution programs, such as Majordomo or ListProc.
