personally i luv there view online feature, i never like saving the doujinshi anyway (less things for freinds to find out about).
Though lately i've been checking into another source, 4chan, if anyone's heard of it there hentai, ecchi, and anime boards give out links everyonce in a while to rare doujinshi. Though u gotto keep at it as there is a lot of ,scuz my language, crap on the boards.

And please, don't visit random.... just dont.
