Like AFusion mentioned earlier, I'm also from
Tokyo-Nights (founder/owner). Our forum, which began in Feb. 2004, has well over 13,000 members since its creation. While the amount of members aren't a true indication of a board's success, we've strived to create one of the nicest j-entertainment sites you can find. One of the main focuses of the site is jpop (japanese pop), but we do have other sections which appeal to anime fans and other asian artists.
After running such a site, I'd like to perhaps help you out with yours. I do like the varied features and the fact that you were able to create all by yourself, so if you do need a helping hand and don't mind working with someone who runs a massive site of his own, then feel free to contact me back or leave a message here
