Hmm, I have to say I'm not a fan of the new look.
The colour scheme looks fine, as any Colour Wheel would no doubt show, but it's the state of the font that's getting me down.
The style and size of the font just looks amateurish, and I have to scroll out 2 levels in Firefox just to get the forum looking decent enough to read.
I would have preferred you guys working on C2 rather than on something which could easily have waited 12 months.
A corporate identity is obviously important, but it has to look professional.
And there really wasn't any reason why the old look couldn't have stood until you were ready to release both C2 and the new look.
Still, it's your baby.
