Mango is a language program that you can use for free though your local library.
The
Mango website allows you see if your local library is offering this program for free.
So far I'm really enjoying this program because, it teaches you actual conversations in Japanese and I actually feel like I'm learning more effectively this way.
The only downside is that I wish I were able to interact with more people learning the same language like on
livemocha. Also you can only access Mango for Libraries, through you local library's website.
