I see no thread about the new forum design... or maybe I'm just blinded by the bright baby blue background.
Please move this post into the right thread if there is one and I just missed it.
I really like the new design as it fits the main page. It is (like always) unusual regarding the colour choices but by now this has become a trademark (evil word)
of CS and I love it.
Everything is pretty huge (avatars, text, etc.) but I think it's just unfamiliar and you can adapt to it.
I like that you now see the avatar of the last user posting in a thread. This really helps with orientation IMO.
All in all: Thanks for this pretty style upgrade!
