In Israel, many coloured minorities would prefer to use the site in Arabic. While we at iNat Israel speak Hebrew and are working on a Hebrew translation, we would like to eventually provide an Arabic version as well. It would help lower barriers to inclusion and allow for a more diverse user base. We do have some Arab, Bedouin, and Amharic-speaking users, but we would like to do more to support these marginalized groups.
I am sure that there are many other countries who have coloured minorities, whether native or immigrant, who would prefer to use the site in their mother tongue. I think providing more support for translations may help. Fortunately for North American users there is already a full Spanish translation.
(On that note, any Arabic-fluent users who can help, please reach out to me in a private message)
