I think the new forum is great, but I agree there needs to be some work on the styling. The colors aren't bad, but it would be cool if they were closer to the Godot brand. I also think there are some low contrast issues (for example, the preview on a post is hard to read, and on quotes, among other things). And the text size is rather small. It Could probably be bumped up 2 points. But overall the software is very much the best in terms of available FOSS forums, so I think with a little work on the CSS everything will be fine.
