hi,
my username has changed.
I can still log in with my openid and pswd.
could be a technical glitch?
how do I restore my username?
If you click your username on the top-bar, to get up your profile, there's an edit button just to the right of the words "Registered User", this will let you change your username (and other details, obviously).
As for why it changed, I don't know - anyone?
We are no longer inferring display names from openids; if you want a display name you must set one.
This is by design and will remain this way from this point onward.
Why?
without a display name set nobody can @reply to you.
it exposes part of your openid identifier.
apparently a solution here Username missing from Launchpad OpenID - replaced with user{number}
