I would like to receive my lessons at two different e-mail addresses.
That's an odd request. Sorry, you cannot receive your lessons at two different e-mail addresses.
Note however that you can access all your lessons and corrections from your 'Cahier de Cours', under the 'Pedagogy' tab, at any time (What is the 'Cahier de cours'? How do I access it?). If you receive your lessons using your professional e-mail address for example, you can still access them from home this way.
Of course, you can change the reception address for your lesson at any time from your 'Cahier de cours' (I would like to change the reception address for my lessons).
