Pinning this to the top as a lot of you are working out how to change your EA Forums username currently.
We have detailed steps on this right here:
I don’t think my account has transferred over properly, although not sure how this all works. My username over on the other forums is Holiday, and I got EA_Cade to update my email address over there so not sure what’s happened!
I had to update my EA ID to better reflect my old forums username. I followed EA_Nils' guidance. Maybe this will help:
"Visit https://myaccount.ea.com/ and update your EA ID. If you then log out and in again on the forum, your user name should update."
This guidance is posted here: Getting Started - Welcome to the EA Forums! | EA Forums - 26
