Are there any speakers of Yucatec Maya?
I would love to learn and practice Yucatec Maya with a native or someone who is good in it! :)
The Duolingo forums aren't great for finding language exchange partners. It can be worth posting in the individual language forums, but even then, you rely on someone happening to be looking for a language exchange partner at the same time as you. Have a look at this post about how to find language exchange partners: https://www.duolingo.com/comment/1444346.
There are sites dedicated to putting language learners in touch with each others. Have a look at the list of language exchange sites on the Multilingual learning resources page on the Duolingo Wiki.
I don't speak maya as well as I used to but I can still teach you the basics if you want. The grammar can be kind of weird if you're more accustomed to European languages and I can totally help you with that.
