Yes, what Liscab says is correct. We can't have a regional section especially in another language unless there is a board Moderator for it.
What generally happens is that someone from that area comes to us and says, "Can we have a forum?". The answer is usually yes, if we think we can rely on the person who will be the
mod. If they don't moderate it properly, it can cause problems for us. With the Korea board (in Korean), we have staff living there so it is easy to look after.
