Just like there is nothing unique about this site that sets it apart from others like it. However, think what you will I have no problem proving your arragance wrong.
Not to mention my answer was acceptable to the person who asked it as they are still an active member.
RMRK, and the other major RPG Maker sites filled a niche. Anime is not a niche, it's too widespread an interest to be a niche, therefore you need more than just a webpage with forums to get people to show up, as you have, guess what, actual competition on the internet.
The same thing applies to RPG Maker sites. There are dozens that people try to form on their own because they see how successful RMRK, HBgames, and etc... are. They fail and shut down because there's no reason to go there, when there are more active sites already in existence.
You're essentially trying to get people to switch from a well-known product that they are used to and invested in, to your brand new, untested, somewhat shoddy looking product, and you can't even tell them why yours is better and deserves their time.
If you want to succeed at community creation ( which apparently you do, given the frequency by which you post new community webpages here ), then you need to understand marketing and how to draw people to your site. Take some criticism and learn.
