You guys see it yet? So many of you guys asked for it...and now it's here! You have to be registered (it's easy and free) and then just go to your "User CP" page. Currently only works for the new releases page, but it'll work for the rest of the site soon!
Note: Only works if the release has series info (unlike some doujinshi releases...) and the series info HAS TO BE CORRECT. If you guys see any series with an incorrect genre, please change it.
