Update! We're back.
I had to do a clean install to make sure everything was safe, and there was a bit of panicking about being able to retrieve posts and users. In the end everything is back, though.
Just working on bringing a few mods back to finish things off.
Everyone, thank you for your patience. I took much more time getting the forum back up than I had any right to - the attack chose a bad time to happen.
EDIT: If you like the brighter themes for browsing, I've added 'Kani', a very readable, stylish light theme. If you try it, let me know what you think it.
