There is a user name and a display name.

You can change your own Identity.
You can change display names - yours and members.
However you may not want to do it unless you can actually see the person's name in their email address.
For other members, you can change it in Admin, Members.

See this page for instructions - Identity (Your Profile) section.

Feel free to send just the part you want to your members.
