If you are a member of AZA (password is your member ID number), you can login to NAGNOTES through the AZA website (www.aza.org) and change your contact information without having to go through the list administrator.  Also, you can globally change your addresses to all listserves you're subscribed to through AZA at the same time, which makes things easier (and sometimes a lot faster) if you've had an email change.
