So first off, I REALLY like what you're going for! i feel like my eyes don't have much trouble naturally following a path down the page. I feel like i can go from left to right, and then right to left again with relative ease.
I think my favorite part is where it says "locations" cause it's not something i've seen before! is that all one category with all the forums and subforum shoved into it?? im very fascinated, i'd love to actually see that in action, it looks like a neat way to organize.
Now, my only real issue, and this is a personal issue with me, but it's so.... Dark. I'm not a fan of dark skins. I feel like there could be more contrast while still keeping the dark colored scheme, but that just might be because I'm looking at it from this image as opposed to a full screen site like I normally would be looking at. If there was a light version though, I'd snap it up in a heartbeat? Like take all my money haha I really love it otherwise.
