Actually, I believe that is yyyymmddhhmmss format, so it is the eighteenth of January 05 about 22 minutes before lunch. Perhaps the site admin discarded earlier changelog data, or perhaps the changelog option was just enabled around that time, and there were 88 subscribers then. You'll need to confer with the admin to discover whether earlier data can be accessed. But for statistical purposes, oriented toward promoting the benefits of the list, maybe omitting the first four months (when things were slow and/or confusing for new participants) is a good thing; just refer to the most recent full year, or use calendar-year-05 as your basis for comparison and discuss how things have progressed since then. >>> [log in to unmask] 10/12/2006 2:48:46 PM >>> Thank you, Francoise. My next task is to figure out how to apply the Rexx program for Windows! The Changelog file records all transactions back to this one: 20050118113840 SUBCOUNT 88 This puzzles me because, if I'm reading correctly, the date is January 1, 2005, but the list commenced operations in October 2004. One explanation would be that the site administrator removed the changelog file for some reason and didn't replace it. I have had some technical problems in the past, and the people who served as site administrators during that time did indeed remove some archival files to get the list working again. But they replaced those archival files, at my request. Is there another, more likely explanation? Can I get a complete changelog file back to October 2004? Thanks - Ian
