[[-- Translated text (es -> en) --]] Colleagues, at https://www.jornada.com.mx/2021/10/17/politica/011n1pol reports of a major effort to use the Internet (an app) to avoid the loss of an indigenous language, O'odham or O'otham. Many of you maybe They know this ethnic group by the Kikapú name or variants of it. At This article also mentions other languages such as Chol (there is a distance of about 3,000 km between the towns of the first, in the US-Mexico border on the Pacific coast, and the second, on the Southeast, Gulf of Mexico coast) as well as climatic differences extraordinary. I return to this point because a few days ago in the WhatsApp group it was commented another matter related to this same topic and wanted to draw attention to that we recover it in the discussion list to which we all have access and the record of which remains. There is an important point of UA and IDNs pending. Greetings to all / you.
