Huge Security Issue!

I would also like the ability to change a username.not to be confused with nickname i would like to see the ability to change user name.

New user here. I want to be notified when a login to the account has occurred. Even if it’s a failed attempt, I want to be notified.

Is this possible?
If not, can this be added?
We are talking about customer security, right?

How much clearer can it possibly be that the USERNAME (not the nickname) needs to be allowed to be edited and changed by the USER. It has been 6 months since the original message and still the problem EXISTS!!!
