When you register with the Commons, we require that you use a CUNY email address. But once you login successfully, you can change that email address to the address you normally use and receive email notifications and (if necessary) reset your password at your familiar email address.
To change your email address, login into the Commons, hover over your avatar in the top right hand corner. Select “My Settings>>General”:
Change your “Account Email” and save changes. This will then be your Commons email address.
