I just registered for the message board a few days ago. I encountered a certain amount of difficulty registering, because of the required mail area / zip code field: in Taiwan, where I live, this is usually a three-digit code, although there is also a five-digit code that few people use. I tried using the three-digit code, and couldn't register. After asking around, I found the right five-digit code, and then things worked out. This raises the possibility that for areas that use a code with three or fewer digits, the registration field is too restrictive. Perhaps in a newer version of the programming for this website, this may be taken into account.
