So after a glorious moment of total idiocy - in which I forgot to pwd before executing a rm -rf * - old.atc has been repaired and is back to its former glory.
"Former glory" being the site as it has been since July. Hopefully I'll have something new squatting in the domain root before too long. It'll probably look a lot like the current site, with some navigational changes. I'd be contemplating a complete aesthetics overhaul, but I really haven't been able to improve on the current flavor and I really, really hate dealing with CSS.
The site's been mothballed this way to (hopefully) make the Second Edition of The Dualist easier to implement. We'll see how true that turns out to be in the coming months.
