Right, i searched around for an hour or two, and then looked manually for awhile too, without finding any links to this rather awesome site.
http://doujinshi.mugimugi.org
Basicly, if you go into content, you can search for most of the diffrent kinds of genres there is on this site. The drawback? It only has titles, author info and such. No link to downloads or anything that could help us get the H-mangas, or doujinshis. Still, quite a nifty site.
