Well now that's an idea! But the question really is: ARE there any unanswered posts here at Digital Point?
Could be many valid reasons for an unanswered post. So for me, I would not want to log-in and see a list of those, nor a link to those.
Just do a search for threads with no replies On the advanced search page, choose find threads with at most 0 replies. Don't put anything in the keywords field.
That link doesn't work. Here's a better one that does work: http://forums.digitalpoint.com/search.php?do=process&replyless=1
