It was the old Legacy background, before the site crash. It wasn't a hard black background. It had more of a speckled feel to it, but it was still very dark. I liked it, but like I said, I understand that we're not going back to it.Speckled background? Did we have a speckled background? I honestly can't remember!
What's really strange is that while the fonts are just slightly different, the menu bar at the top (What's New, News, etc) is about 50% as big as it used to be -- which is a pain as the "Forum" button is much smaller to aim at.
As I mentioned, that's not a style thing. That's on all styles and is because on smaller screens they literally do not fit. The whole layout breaks. That was a change which was long needed.
I'm very dissatisfied with the whole vBulletin navigation layout (a navbar, some additional buttons, etc.) - it's overly populated, messy, and not particularly intuitive.
It was like that, yes. Wasn't so much speckled, I guess
