I was browsing Wikipedia and I came across this language: http://www.omniglot.com/writing/baluchi.php, otherwise known as Baluchi, Balochi, Baloci or Baluci, is a language spoken in Pakistan and Iran with around 7 million speakers. There are two dialects: Eastern and western.
There's probably not any native speakers (here on Duo, anyway), but I thought it would be worth adding to the Guide.
ISO 639 identifier: bal
If anyone does speak it, or knows any resources, let me know, I found a Memrise course, but that's it. (I didn't look very far, but anyway.)
