Changing my Forum’s Username

Hi all forum users,

I have recently gone back to Apple online support communities just to know that it is a wonderful place know more Apple enthusiasts and help the ones in need.

A few years back I desperately wanted to get onto the community so I randomly plugged in a username, just to know I can’t change it. However, now that I want to learn more and help more through this community, I am wondering whether anyone knows how I can get my username changed (cause I can’t find the button to change it in “edit profile and preferences”)

Any help is highly appreciated!
