Midchuck: Actually, there is such a list. Go to the drop-down menu in the upper corner of this page. (The default option is "Quick Links.") Open the menu by clicking the little triangle. When the menu opens, select "Unanswered Requests" and click "Go." That will bring you to this page.

Not all unanswered requests are listed here, because the list hasn't existed as long as Mudcat has, but there's enough there to keep you very busy.
