I recently added the Topics= keyword and a Default-Topics= All keyword to a list but forgot to retroactively set all users to Topics= All. I suspect that some subscribers then missed some of the announcements. I should have known better but just want to double check my "reality". Specifically, what happens to a subscriber with columns 93-94: a. ' ' (blanks) Ie. subscribers from BEFORE topics support in LISTSERV b. 'AA' (x'C1C1') Ie. subscribers from AFTER topics support in LISTSERV This is apparently the "default default-topics" entry I THINK that AA must mean "none" or something. AB is "other" and the blanks seem to be seen as "all" (which is coded "//"). Sooo - to correct my boo boo I think I have to extract the "AA" entries and send the back items to them, right? Would "all" be a better "default default"? Or rather, to have " " and "AA" handled as "//"? I want to make sure I'm not missing something as the list in question is very large. Thanks! Marty
