When changing the header to "single" RENEW are all sub'ed users asked to confirm ? I would suppose so. What about 3-Monthly ? If a user subscribed yesterday and there was no RENEWAL , would this user be ask to confirm ? Or would LISTSERV wait for the 3 month anniversary of each subcription starting on the date of the change ? i.e. each user asked at his/her anniversary and then afterwards quarterly ?
