The new Foreign Communities section looks like a good idea. We have had several non-english speaking members on our forum and it is sometimes difficult to understand questions or convey answers to the member. Once a foreign member notices the section, they will probably invite friends to join. One concern of which I am sure you are already discussing. You will need Moderators who understand each language well enough to pick out threads or posts which may go against forum rules such as warez or porn, etc. Just a thought.
