Can't see m1234567 user names in control panel

Does anyone know where to find the old user names? I can’t find them in the control panel anymore and I know they used to be there just a few months ago. I never wrote them down and now I need to access an existing account and I can’t login without that m1234567 name.

that name is not suppose to be required any more. You should be able to log in using the email address of that user name.

Thanks. It looks like the old user names are indeed retired.
