Marc, A LISTSERV password empowers you to use the AFD and FUI commands. That is, they cannot subscribe to a file and generate load on your server unless you accept to define them a password, except for local node users and except for users for whom you are the nearest LISTSERV -- in that case the PW ADD command is automatically accepted. Please note that this is a USER-TAILORABLE exit, LSV$PW, and I only provided a sample one which I think is reasonable. Feel free to modify it to suit your needs, it won't appear any more in the future ship- ments :-) Eric PS: I'll reply to other questions later on the list.
