Please clarify which username you’d like to get, and I’m sure @VHTV_James will gladly help you

Can’t yo just click on you initial on the upper-right of the screen and then click on preferences to change name?
Welcome to the forum, @henrik1966!
You have 7 days to do that after registration. I’ll elaborate on that next week & we may set up a process of nickname changing requests. Long story short: Frequent nickname changes = no good.
