You should also sign up for an alumnae email forwarding address (username@alum.barnard.edu). All email sent to this address will be forwarded to your replacement email account.
If you already know your alumna username and password (not your UNI), you can sign in here to activate your e-mail forwarding address.
After you log in, go to the "Email Addresses & Interests" section and follow the instructions.
If you do not know your alumna username and password, please visit the alum site to sign up for one. After you have it, you can follow the link above to set up your alumnae email forwarding address. Please note that you cannot set up your forwarding address until late February your senior year.
