In order to sign up and apply, you need to do these things:
1) Go onto the Duolingo website and register an account. It is important you go on the website and not the app for reason that will be explained soon
2) choose a language to learn. If you do want to actually learn something that's fine. If you don't want to actively learn something that's fine too, just choose any one you want; it doesn't matter.
3) once you get to your profile, go to the top of the screen and click on
home, next to the big
Duolingo title card
4) On your homepage, in the top right corner should be a central hub with (going right to left) your account name, your profile picture, and the flag of whichever language you've chosen. Hover your mouse over the flag, and information about your progress will appear in a little speech bubble
5) go down to the bottom of this speech bubble where it says
add a new course and click on it.
6) you will appear on a page with a grid-list of all the language courses that are offered. Scroll down to the bottom, and you should see an area that says
Language courses made by the people and a blue bubble that is labeled
contribute to a course that you click on. This feature is only seen on the website and can not be reached on the app!
7) this blue bubble will take you to a new page called
duolingo incubator, which is exactly where you want to be. At the top of the page, underneath the title, is a white bubble that is labeled with the same
contribute to a course as the blue bubble beforehand.
Once you click on the little white bubble it will take you to the volunteer application form (almost done!), and now you simply fill out said application.
9) the course you'll sign up for is "
Dothraki for
English speakers" and if you're willing to moderate that would be fantastic.
10) All you do now is specify your native language, answer a question in Dothraki, translate your answer into English, give them your email address, confirm that you're over 13 and submit your application.
And that's it. Hopefully I'll have enough applications from other Dothraki speakers such as ourselves in order to start this project. Thank you so much for your time, and I hope you have a fantastic day!
