Displayname

[All Seeing Eyes]

I registered a second account with a chosen username, then filled in the fields for what i assume is the display name, but typed the wrong letter (M instead of N), i didn't notice until the account was approved.
Reading the he;p sections etc, it says i can't change the username without deleting the account, but i'm happy with the username, it's the displayed name i want to change, is that possible ?

It's the displayed name that others see that i want to change.

Deleting the account and starting again would mean losing the chosen username i assume.
