I've just seen the reports (yours and from others) and added the variation with Hello/Hi/Hey/Good day.
Thx a lot for your help reporting it!
When your answer is rejected but you're 100% sure it's correct, please only report it with the option during the lesson ("Report a problem" -> "My answer should be accepted"), without mentioning it in the discussion as it doubles the work for contributor: checking reports in the incubator + reading discussions. Hence slowing down contributors in their work to fix issues.
Thanks a lot for the excellent advice, Jrikhal! Now, I am reporting some variations if rejected, only with the reporting tool, as at the same time I try to read more about the Navajo grammar. Thanks to all the contributors and also for the moderators' attention on this course. :)
The course is so new. If there is something you can't report, I wouldn't worry about it. Just try to remember how you'll need to answer it, vs what the correct answer is for now. This course has more contributors than any other course. I'm sure they are also going through it and documenting things to update once they are able to do that.
In the past, the community was not allowed into courses until they were out of beta. So many people asked to be let in at such a rough stage of the course, that staff finally agreed. But, it's important to recognize that this is a very rough stage for a course, even though we are now allowed to help test it. If it is causing too much stress or frustration, it is ok to wait until the course has been fixed up a bit more. Courses that have just graduated from beta are still rough, but less so. If you want a significantly smoother course, it often takes about 3 years from release for courses to be finely smoothed out.
I recently found an error in the course myself. It was a question that had a set number of boxes to choose from. I put the boxes in the correct order to form a sentence. I was told one had a typo. Only, it matched exactly the only box they gave me. And, there wasn't an alternative. So, I know that my answer was correct. When I asked a contributor what to do? I was informed that particular error was not an error for the contributors to fix. Rather, it was a bug to do with Incubator interfacing with the course or something like that. The only option was for me to submit a bug report. So, if you see something that is absolutely a bug and not an error that can not be reported via the flag, like in my case, please use the Bug report form.
The "issue" with Navajo if the course is being by native speakers is that most native speakers can't spell the language correctly and leave out many spelling details (like they give díí for "four" when it should be dį́į́ʼ) or sometimes insert inexisting segments (like yį́yą́ instead of yiyą́). It hurts learning a lot because it makes the whole grammar so confusing.
@Sam, there is no audio at this time. The present version of the Navajo course is a mini beta version. There is a longer course with audio in the works. Check out the announcement here: https://forum.duolingo.com/comment/29175331
In the future, please remember to only use Sentence Discussion forums in these ways. You're welcome to use the Troubleshooting forum for technical questions. Thank you! :)
Edit, a member of the community has created audio for some of the vocabulary from the course. More about that here.
