... because I'm not a computer scientist anymore and i want my username to reflect this. I'll register myself with some other username
In certain circumstances Kwun an change your username, previous examples being where a user wishes to have their name protected if their username was their real name. Your reason unortunately does not qualify for this. Unfortunately you will have to stick with it.
I have a spelling mistake in mine and I don't even qualify cause of that....you should think you're lucky!
