Thank you for such detailed descriptions and helpful resources! Maybe I still have question about the tone marking concerning definiteness, but I’ll rethink after learning about it with your article later.
About the fan zine I mentioned, it is planned to be tiny staplebound booklet (without charge), and contain short pieces from several learners/fans of various languages (though they may be written mainly in Japanese or some auxiliary languages). I heard online distribution is also planned.
Unfortunately, the application period for upcoming issue had ended already, so I’ll apply again for the next one (probably around next summer at the earliest), with more confidence in the N’Ko part. Thanks for showing interest!
