Or, more accurately, duolingo.com.  It’s a web site where you can learn, for free, another language. I went through the English to Spanish program. Rocio, sometimes, does the Spanish to English (hint, hint Rocio).

It’s free, it’s fun, its well-done and by using it you are doing something useful. Why you personally are not “the product” (you are the product, for example, with Facebook) as you are learning you are helping translate Internet content. It works on regular computers but there is also a specific tablet/phone version. I personally like the regular version (which just runs in a web browser) best but Rocio tends to do it on her tablet.

There are lots of language choices. They just added Russian and are supposed to be offering Klingon. Check it out.
