Hi, Leandro, nice to meet you. So we have 2 brazilian moderators in the forums, that's cool!
I'm originally from São Paulo, but I currently live in a smaller town in SP state.
As for the language, good question, I was asking myself the same thing. We'd better ask Steve about this as this hasn't been addressed yet. But in my opinion we should keep all posts in English, as it's the "official" forum language. I understand that we could benefit in some ways from posting in Portuguese on this thread (and other threads that are meant specifically for brazilians). It would encourage those who don't speak english to participate in the forum and we would be able to build a larger community of brazilians inside the Local Groups forum. But on the flip side of that, if we use a language that other members don't understand, this would restrict their interaction with us and I don't think that would be a good idea. Not to mention that it would cause moderation issues (I would be able to moderate posts in portuguese, but it would be completely impossible to moderate posts in languages I don't speak, so this pretty much kills the possibility). And also, with people from all over the world coming to this forum, if each "sub-community" in the Local Groups forum starts to post in their own language, this will cause segragation and restrict interaction. So I really don't see how this could be a possibility. But anyway, I will ask Steve about this just in case so that he can address this.
