And no, Im not learning french through rosetta stone. There are many language classes in the city, so I prefer to go that route as its so accessible. I feel because I already have basic knowledge it will be something I can pick up quickly as I have the time to really do it.
As for a third language, I dont think rosetta stone is that bad I dont know ive never used it, only looked it over. But I think it can teach you basic conversational of whatever language you choose. But I could be wrong.
