I dun sure this should go in the help section but i wana suggest one or two idea:
1.group the types of manga/dojinshi.
{reason: getting bored to search for futanari(dickgirl), milf and sometimes lolicon(sometimes i dun like this).
oh,yeah i the site is great!~
*cough* no futa action *cough*,*cough*
There was a futanari section under "Fetishes", but it's currently down right now with the rest of the image section. As for lolicon, material depicting underage girls (or boys) is not allowed on the site.
There is an edit button for posts, but it doesn't stick around for very long. There is also a manga edit information button, but only certain users with 10+ rep can use it.
On another note, lolicon is pretty borderline now. I've seen some deleted, and some kept.
I think classification for the manga [into genres] would be cool, but I'd love to see "Characters in this manga" implemented first.
