Ya, i was just wondering if your putting doujin's or doujinshi under manga, or under a category when searching for manga. That and would you allow a hentai category, it seems like you already have a hentai game genre. I know this web site doesnt show any of that so younger viewers would not be able to see it, a lot of doujin/doujinshi are considered hentai too and some are just like manga except they were not published by famous artists. There are different doujin's/doujinshi, but the ones i typically read are adult. This site was originally made for anime but since you went so far as to put in manga I decided to throw this idea in.
"Just an idea"
