I forgot to mention that the tutorial was not originally meant to be released before the conference :-) The LISTSERV.NET domain it refers to has not been set up yet (the domain registration form was sent yesterday). So for now you should still use the ...%LISTSERV.BITNET@... trick. By the way, I would like to thank all the people who offered to host secondary name service for LISTSERV.NET. Princeton were the first to reply, so that is where the secondary will be. Eric
