I've created a 'Vector' category under 'Other', from now on please submit your vectors in that category. The type will still be 'Doujinshi'.
If you have old vectors and want them moved to the right category, paste the link to your work in this thread and I or one of the other mods will move them for you. Thanks :D
[edit] Nuri has made another section: Unknown Ecchi section. From now on, all unkown ecchi scans will go in there. People can now surf the female scans section safely XD
