Oh, the guilty pleasures arise...
I'm more infamously active in a site entitled Rule34 as the user pl0x. Most recently I've dumped a handful of new hentai into the CT/CC sections AND one image for Radical Dreamers of all things.
There's recently been a release of a particularly painful Flea doujin that I only uploaded for the shock factor. I do alot of my own drawings as well, but most never get submitted anywhere because I don't like the quality of my art and/or get embarassed.
So if people really want to go see what I've found (and I've been scraping the bottom of the barrel for months here) search up Paheal's Rule34 page and search the tags with proper underscores (chrono_trigger, etc.)
Also, Hentaipalm Forums has a good bit of content, probably not as large as the Rule34 one. There was, I recall, a hentai magazine released once that had a short CT chapter in it. I think it's over on E-hentai, actually.
Rather promisingly to me, however, is the slow but steady rise of fanart (of all types) at my favorite slush pile, Pixiv.net. There's some really beautiful stuff coming out due to the release of the DS version.
