Hi @RBA,
Welcome to the DocuSign Community!
We are glad to have you here and can't wait to help share as much knowledge as possible.
I am sorry to hear that you are unable to edit your user name, but I will help you locate the root cause of the issue.
Are you editing your user profile in Settings>Users>Actions?
If that is the case, try editing it in your user profile instead. You can find this option by clicking the profile picture or initials at the top right corner of the screen and selecting Manage Profile.
You can find detailed steps on this process, here:
Change Your Name
Feel free to let us know if you need further assistance with this.
Thank you for using DocuSign, we hope you have a wonderful rest of your day!
Best regards,
Alejandro R. | DocuSign Community Moderator
