At the moment Google Code displays my username as a not-very-well-obscured version of my email address. This setting can be changed at https://code.google.com/hosting/settings - it can be switched to show my full email address, or my "Google Account username". By default this username is the prefix to my email address. I want to change this to something else.
If I look at https://accounts.google.com/ManageAccount I see an option to edit personal info without creating a profile. The "Edit personal information" page includes an optional nickname field. When I change the nickname, it does not change the username value in Google Code.
I do not want to create a public profile for my Google Account. Can I change the Google Code username value?
