How to change Unity Discussion username?

Can any moderator help me to change the username?
Or let me know how to delete my account if cannot change username.

You posted this in the normal question section. There’s a feedback section about discussions itself. A meta space if you will. There was already a question about changing the username.
Just make sure you log out of discussions and the name should be changed when you log in again. At least that’s what was said in that other question and people have confirmed that it worked.

login your account in above link which i provide then click on the right corner of your profile
go to my account then change your name and user name which you want to change

Hi. I’m asking about changing username of Unity Discussion (Discourse), not Unity ID.
