After a very long period of DynaHack-related inactivity, this website has finally become structured the way I wanted it all along.
The old DynaHack page was made in a rush for ARRP 2013, using a stock GitHub Pages theme, and as it turned out, those themes were not Jekyll-ready, meaning that making a multiple-page site would involve a lot of copy-and-pasting, so I put off fixing the website for a long time; it's only now that I've gotten around to it.
As for DynaHack itself, development will resume at some point at my discretion. If you're really eager, keep an eye on the commit log, which shows all code-related activity for the game.
