About the Portuguese translation of the page..
Not gonna lie, it's not... perfect. It's mostly Brazillian Portuguese and in some cases, it's not even translated. Not sure what I can do to help, I'm just a 17 year old guy, but if there was a way I do know my way around the English language (and I'm Portuguese). (At least well enough to improve the translations a bit, haven't taken the proficiency yet but I did get an A in the CAE).
It's not really that important, you probably don't have that many users who do want the page in Portuguese, but still. Just speaking my mind.
