You've possibly noticed ES switcher in articles.
If not - we recently introduced the option to switch to the Spanish version of the article.
Everyone is able now to add a translation to an article on the Developer Community.
If you want to add a translation request author's permission on the articles page in a Translation tab.
If the author grants the request you are able to publish the translation with your name on the Spanish Community site. Spanish Community is operating in a "beta version" mode.
if you are an author you receive the notification by email about the request from a particular DC member. It's your decision whether to grant it.
If you want to translate your own article request the permission from yourself and grant it )
The same thing works for Spanish Community site - you can translate the Spanish article in English. Be sure, you know both languages well! )
Looking forward to see your articles in Spanish and stay tuned for the official launch in May 2019
