Please excuse me if this seems like an amateur question . . . I recently inherited maintenance of a list and web subscription interface. I am noticing that since ListServ is case-sensitive, users are actually allowed to subscribe twice or more, depending on case variations. Is there a way to find out or generate a list of dupes or better yet, convert case of email addresses upon subscription?
