The listserver may send a confirmation email to the address you give here. Unless you reply to this confirmation within 48 hours, your attempt to sign off will fail. This may happen if you are not reachable at the address you gave. If so, please contact me at sidsnet-request@home.ease.lsoft.com so that we can figure out how to sign you off correctly. Please do this from email, rather than from the web -- we are more likely to get a correct reading of your email address that way.
