I don't understand why the communities page now appears half in English and half in another language. Surely, if you have decided that it should be in a particular language, why only change half of it?
Secondly - if you are going to assume and force the language of the page - PLEASE - have some option to change it. (This does not mean presenting the word "Language" translated into Chinese or whatever other language so it looks to me the same as the rest of the content - put a flag symbol or something that everyone regardless of language will understand). Saying login doesn't help either, because how am I supposed to know that "开始会议" means login?
