Thinking it would make my Skype user-name easier to remember for patients I started it with the letters "dr" and followed with my name. Then a patient pointed out that her husband, who does not know that she suffers from a mental illness, might see the user-name on the computer, arousing his curiosity.
I plan to change my user-name, which appears to require that I start from scratch with a new account, probably a different email address. It will be worth the trouble.
I suggest if you set up an account yourself that you pick a user-name that has not association with your profession.
