username change

Hi! is it possible i can get my url changed? I previously sent an email to [email protected]  but didn't get reply or anything. I feel uncomfortable w my current username, i really wanna get rid of it. I'd much prefer flytxsky to my current one.

Sorry if this is the wrong place but i cant find where i'm supposed to request this. Thanks in advance!!! ♡

ohmygod,  i'm extremely grateful ♡ thank you so so so much ♡
