As a minor suggestion I think the forum list could benefit from tighter padding/margins on desktop. As an example of what I mean, check the forum list on the left side of BlenderArtists:
Personally I find this easier to look at, it’s more condensed and the fonts/colors aren’t all bold and high contrast.
Also on the subject of the above screenshot, I think it would be awesome if you had a featured posts bar at the top like Blender-Artists has (its the row of square images toward the top of the page)
