As a regular user, you will not be able to change your login name. You will need to contact the administrators who may be able to change this for you.
Please note: this is different from the
Display Name, which users
CAN change on their own via their preferences. This change may be subject to administrator approval. (For more information, please see the topic:
How do I change my display name?.)
