Comment vous vous appelez

The lesson is very comprehensive -- 

"It's tempting to translate Je m'appelle... as I call myself... but despite this being its literal translation, this is not correct.

I call myself... implies one's real name is something else, or a choice over one's name.
-> My real name's John but I call myself / everyone calls me Jack.

In French, the equivalent of this is Je me fais appeler..., which has the same implication of choice over the name."
