The difficulty is in the authentication. The WWW server only has an IP address. It needs to know the person's e-mail address, the name of the list, and somehow it has to verify that this person is an owner. Then it must acquire the information, present it to the user, and so on. Building a PUT request and sending it to LISTSERV is not difficult at all. In a dedicated interface, the information necessary for authentication can be saved in a configuration file, and the interface could keep a list of the lists you manage. With a WWW interface it would have to be retyped every time. Eric
