@nilo, thanks for doing this!
I see that you have translated nearly all the modules into pt_BR.
I’ve always assumed that the right way to do things is that when we have a language, and a country specification, that the majority of the translations should be in the pt locale, and only things that are specifically different for Brazilian Portuguese would be in pt_BR. However since Transifex does not appear to work this way, and you’ve already done the complete translation, I think we should keep it simple and just pull in the entire translation as you’ve done it. Perhaps at some future point someone can cross-check and harmonize the pt and pt_BR translations.
On this thread we’re looking at actually automating the process of pulling in translations, FYI: bamboo setup for transifex
