Actually, it probably just moved. If you're looking for the Radical Dreamers web-manga, it's still around but the name has changed. It's now called Eidolic Fringe and can be found at http://bonsaimechafactory.org/eidolicfringe.
If you're looking for Laura Galiffe's page, it's now at http://bonsaimechafactory.org/pangaea
If you violate our copyright or piss us off, we'll send Hinoki after you!
