NWOTN3 already exists... plus... I don't think the forum permissions allow anyone to copy the forum structure. If you haven't checked, the forum ideas and structure (at least the basic one) belong to me and the only person besides me to be allowed to use it is Shiro and any other person he allows, which I don't think it's the case.
If you don't like this management on this particular forum, go to another one or if you want to make yourself one, make sure you do one yourself, with stuff of your own.
