Curie is for English language or at least bi-lingual English language posting. Curie does support some sub-communities by following the vote of the community's curation team, and some of the regional sub-communities do support non-English posting; you can see the full list of the sub-communities supported by Curie and the users who head up each sub-community in the weekly update published right here on @curie blog every Sunday.
