4chan's ecchi imageboard meant for discussion and posting of softcore hentai pornography. This board while having good content (you can't go wrong with cute naked anime girls) is fairly empty since shitposters go to /a/ and hentaifags go to /h/. /e/ is a nice community overall and probably the most relaxed on 4chan.
Anon1: Let's have a catgirls or neko thread /e/.
Anon2: I actually have 1.7GB folder of catgirls, I'll put it up on my dropbox for you to download.
Anon1: Holy shit anon, thanks bro.
Meanwhile at /b/...
