Dana - "listserv" is no longer the software that supports speakup. Nobody is on "listserv!" What you need to do is send your request to "speakup-request at braille.uwo.ca" and then I am not sure if it is "unsbuscribe" or "signoff" you need. The new processor is called "mailman" and has taken over the list as of a couple of weeks ago. Chuck.
