It depends if you are trying to say he got along well, but did not know any French. Or if you are trying to say. He got along well, because of the French he had learned. The second implies he got along well, because of the French he had learned, while in France.
Yeah, your right...some of us have way more important stuff to say like...Gungawank, vote down troll, he said hi there, ban this idiot already, stupid, crackpot, pervert troll, you da ***** etc...
