I've been thinking about making two simple changes to the site, and wanted to get opinions before deciding:
Switch the color theme to the classic black text, white background. While what we have is easier on the eyes, it makes some text difficult to see, particularly links. It also might feel a bit more like the old forum.
Move all threads to a single category. My thought process is that realistically, we aren't generating enough topics to justify 6 categories and picking one is an extra step that can isolate topics from users. This would also make the forum activity more noticeable.
