It's a minor change, but I think it would be handy if there was a link straight to the challenges subforum on the main forums page, just under showcase. I've attached a pic of the page as is and drew a red box where I think the link could go.
I would have to agree. It was put where it is to keep everything de-cluttered, since there's not an overwhelming amount of people around just yet. This was a discussion we had when the subforum was first requested.
