We admins are happy to see your involvement with the wikia, but we ask you to avoid backseat modding. That is, if you see someone breaking the rules, please notify an admin instead of correcting them yourself, since it's the admins' job, after all!
I deleted the categories you put on the Hidden Entertainment and MMORPG page. The Starshine Legacy, Star Stable, and Star Academy categories are reserved for pages about things in the games themselves, and the Games category only contains the main 14 game pages. The Hidden Entertainment page is about the company that created the old games, and therefore is 'outside' of the games themselves, and the MMORPG page is about the concept of MMORPG, not the games. Hope you understand!
