or is it just me?
They are working on a new skin. I don't see what's in your screenshot, just a kind of messed up version of what was.
Yes, now it's back again. I believe this is how the forums are going to look in the future.
I like the new skin a lot -- been looking for a way to get rid of the glaring white background behind the messages for a long time, now. The new light gray is a lot easier to read.
Two suggestions, tho:
It's to coincide with the release of cs6, which was released today.
That's what the new skin is all about.
