I've been gone for 2 years, roughly, and I'm planning on bringing in some substantial changes. Mostly they'll be drawing more attention to parts of the wiki that need some more user involvement, and I'll be trying to draw some more people in from Discussions to properly contribute.
I'll also be resurrecting the main page blogs. I'll be starting that reasonably soon.
Head to forum to contribute. I'll be trying to get as many people as possible to vote, so feel free to head on in.
