I am going to be working on some updates to the site and forum in the near future so I just wanted to double check what you meant. Are you looking for a link that takes you to posts that no one has replied to? We do have something similar - if you go into Forum Tools, you can select Unanswered Posts. This takes you a list of posts from the past 2 weeks. It's rather buried though, so I will see if there is a better way of organizing the menu and make it easier to find.
Funnily enough, I just happened to check that out this afternoon and saw your post!
Thanks for the suggestion,
