Any chance there will be Navajo on Duolingo? Navajo played and important role in cryptography in WW2, Navajo people helped defeat the Japanese by just using their native language to communicate. I'd be interested to learn the basics of the language. For historic reasons, it's important to spread knowledge of the language.
I do not think so, considering that there are very few Navajo speaking people left. I think that the Navajo language is very cool though, and i would love to learn a few things, although it seem s like such a difficult language to learn!
