Thank you, Grant, for help on many different questions over the years!
In the process of asking the latest question, I have been befuddled by the system repeatedly rejecting my ID, e-mail address, and password (not for the first time). I created two new IDs to log back in, the latest being GeorgeGeorgeGeorgeGeorge. But I see that the system still thinks I am George31416. And also George(etc.). That begets some questions:
Why does the system periodically reject valid IDs, e-mail addresses, and passwords?
Why is the system keeping the ID George31416 active when I replaced it twice?
As an exclusive Mac user, occasionally I have to identify myself to Apple for matters beyond Apple Forums, as do you all. I am dreading the next encounter with Apple Police, because I no longer know who I am.
