Hi Zé,
I think wordpress.orgWordPress.org The community site where WordPress code is created and shared by the users. This is where you can download the source code for WordPress core, plugins and themes as well as the central location for community conversations and organization. https://wordpress.org/ should have a list of all 100% translated languages and list of all localeLocale Locale = language version, often a combination of a language code and a region code, for instance es_MX denotes Spanish as it’s used in Mexico. A list of all locales supported by WordPress in https://make.wordpress.org/polyglots/teams/ sites. Joomla has a page of its registered translation teams and their informations such as translation team’s official pages and where to download the localized packages.
