It could be done. But as of now I don't know of any duolingo courses. There could be one, but also you could try making one?

I don't know, but it's an idea that the community should look to. 

All non-canon words are going 

Duolingo is a very powerful learning platform and although they mostly stick to real languages there is already a Klingon course in development. To get approved to make a course one must prove mastery of both the source, and the target language, in this case English and Dovahzul.

Mastery of Dovahzul? That's not likely with the booked wipe of all things non-canon. 

Goodbye words...

Is the canon Dovahzul a pretty complete language or do you need non-canon words? I haven't really studied the language in depth (although I would like to). What do you mean by wiping all things non-canon?

From the website? Why? I don't understand.

Ok I read the post about the wipe. Interesting to say the least but I could see how it could be beneficial if we can move forward with a better understanding of the language.

The word revision thread is the reason for it, I think.
