I already stated that the font family Ubuntu is not suitable and sans-serif should be used, which was discussed without conclusion, imo.
I want also to point out that I am rarely visiting the official forum anymore, because I cannot stand the recent colors and elements of the theme. No, the theme is great but it needs to be simplified in 1. colors and 2. elements.
That is a recent screenshot with attention areas:
Don't you see that it is too many colors?
Already the box on the bottom: answer button green, comment button darkblue, tags orange. In one spot?!
Also the question2answer banner is too huge. And it does not suit the theme... just write it as text and make it small.
Furthermore the question list is way too colorful:
blue red green orange next to each other, 4 colors? I know that somone wants to express "best answer given" or "no answers" or so, but honestly, I just care about the question title and maybe look at the answer count. The votes are also not important imo, at least not in the question list.
Well, I suggest to get a designer. Or always have "simplify" in mind, keep it simple. The Snow theme was simple enough.
Just my two cents.
