Do you have a different preferred name that you would like to see in Blackboard, email, etc.? This form from CITS allows you to change your preferred name, as well as potentially update your UMID and/or email accordingly:
Note that this will change your name in most, but perhaps not all campus systems and technologies. It is possible that you will still see your old name (sometimes called a dead name) in some systems or applications. If this occurs, email firstname.lastname@example.org and we will take note and see if it's possible to find someone or some way to get it changed in that system.
Also keep in mind that your default email address in directory (https://directory.umaryland.edu) will define your email address in your Blackboard profile.
