I am doing the rulebooks if you count 18 pages over one month as doing anything.
It's all about the freaking formatting, that and Adobe Acrobat makes some interesting choices for spelling and such.
I'll have to work out some macros or something. It would be almost faster to type it in by hand. Oh, and the tables are a pain in the rear, because of the way I code.
I would love for you to do the Greyhawk material, but I wouldn't mind if you wanted to do some of the rulebooks, either.
I'm working on the DMG, so everything else is up for grabs.
