Old WAGNH is dead. If you want to look at the previous site, I have preserved its final embers with this hellaciously ugly screenshot. Do not mourn, for the old site, familiar though it was, sucked. It was also slow and didn't have a bunch of features that I really like having. If you liked it, that's too bad. It's not coming back, so don't even ask.
That doesn't mean WAGNH 2.0 is perfect though. There are still bugs popping up, things to be tweaked, features to be added. And indeed, things have already changed since launch. Load times should be down, for one, and the comment styling has been changed to look a little more compact (closer to the original version). More change is coming, and it'll all be for the better.
But you can help guide that change. What specifically would you like tweaked? I'm curious as to what constructive feedback the community as a whole can pass on. Emphasis on constructive.
