Props on the Downloads Database restoration!
A key part of CFC!
I also see the numerical prefix that LeeS noted. My guess is it might be related to the version support (which is cool, it'll be nice to have that baked-in), but it would be nice if the most recent version at least didn't have the prefix.
I also noted that the link in Xyth's sig for History Rewritten is not working currently. It looks valid and HRW is big enough that I'd expect it would still be there, so I'm guessing that might be a migration-link-redirecting issue?
Going to take a bit to adjust to the navigation on the left, but I can see it being useful. I do wonder if Xenforo supports expanding a category without reloading the whole page? Ex. I click on Civ III Downloads, the page reloads, click on Unit Graphics, the page reloads, click on Medieval Units, the page reloads... with vBulletin where all categories were visible from the start (which to be fair was messy in its own way for the Civ versions with a lot of sub-categories), it was just one click/page load to Medieval Units. I can think of how that could be programmed in a couple ways, but alas I don't work for XenForo and don't know if they have that option.
Going to have to play around with the shiny new options... that "More Resources From [author]" on the right is a nice touch too. I do agree that the download button should probably be a different color since the gray looks almost disabled. Not sure if green would be a good idea since a lot of fake download buttons on the web are green... I don't know if it would be possible to have that match one of the theme colors?
