Odd, I didn't get an email. Downloading now.
Edit: Improved in several areas (fighter, TWF). Paladin and druid look good, though I'd like to see some animal companion rules.
The ranger -- and this is normally my favorite class -- is, well, a bit boring compared to the fighter. He has many fewer options and IMO the spells don't make up for it. I'd prefer to see more skill focus rather than magic focus, so the range is more than a "wilderness paladin". They could provide more options within or based on Favored Enemy/Terrain, I think, to mitigate this, too.
