Can I change my Case ID?
Once your Case ID has been created it cannot be changed. However, you can get an email alias. An alias is nothing more than a nickname for your Case email address. It won't work as a username to log onto restricted web pages or the like. For example, Molly Q. Case registered the alias "Molly". Now her friends can send email to her to three different addresses (Molly@case.edu, mxc123@case.edu and Molly.Case@case.edu), but her User ID is still mxc123.
