Mango Languages is a very interesting free online program. The instant you sign up you can use it! They have Spanish, French, Japanese, Mandarin, Greek and a bunch of other languages for English and Spanish speakers to learn. Including Pig Latin!

They are currently on beta mode but so far I haven’t stumbled upon any bugs or anything. They are also planning to add more languages, I suggest Korean.

I suggest if you have a lot of free time that you will take a look at the site and sign up. The lessons are pretty easy with constant repetition and a bunch of slides per lesson. Did I mention that it was free?

Good for if ever you want to travel someday.
