Hello everyone. I agree with the Christoph3. There is no need to have 3 languages for the Portuguese. Portuguese(pt) and Portuguese of portugal(pt_PT) are the same language, is the mother language.
There should only be Portuguese and Brazilian Portuguese.
For instance, I am the main translator of elementary OS and in elementary OS weblate there is only Portuguese and Portuguese(Brasil).
Another thing, who do I have to go to for permission to save translations in Portuguese on weblate?
