I have stored updated copied of the handout on LISTSERV@SEARN with minor editing changes. The NSC93US version is now a genuine US-letter formatted printout rather than a hacked copy of the A4 version. There is no reason to order a new copy if you were only interested in checking the document, however please do grab the revised version if you plan to make copies for your users. The LISTSERV.NET domain is now fully operational and you can tell your users about it as well. Eric
