Jacky: I have an alternative suggestion: don't teach this feature of LISTSERV. As you and others have pointed out, it does not provide a valid demographic survey. Then teaching it to a geographic diverse community seems like an exercise in futility. I understand that host names are going to get more "complicated" by virtue (of a proposed) expansion of top level domains e.g. xxx.yyy.WWW plus lots more. /Pete Weiss at Penn State
