Since the format update to the forum, there is now an opportunity to view "unanswered questions" in the modifications space, however, when it try this, I get error 404.
It's still not as good as the older unanswered questions button, as that provided a quicker reload of the unanswered questions index (one click), now the quickest way to reload the index is a right click on the browser's previous pages button, then a click on the index page.
