Oh movey shifty things - impressive. I love the software, now that I'm using it, and I'm very curious to see how FC is going to develop from here on now that we all have superpowers.
One little concern though - I find the colour scheme in the posts harder on my eyes than the old forum. I would prefer that the post content be brighter, as it was on the old forum, for greater contrast with the background. As it is it feels a bit 'muddy' to read. And, although I'm reading this at indoors at night, I imagine it will be tougher to see on a laptop screen in the sunlight (which we get a lot of here in Australia).
My eyes (and I'm guessing others' eyes too) are drawn to the white text, such as the 'Report' link, and the custom title text below our names. If I had a vote I'd say to swap them - brighter post content text, and greyed-out or coloured custom titles and Report links, which are text fields of secondary importance.
Mind you, I like everything about the colour scheme at the top and bottom of the thread pages, with the site section ('Forums') and the thread name in white. And the rest of the site looks great too - not messy at all, and very comfortable on the eye.
