Yep, this #gold already exists... #ItsSimple :-)
Improvement Suggestion
Here is my suggestion on how to improve this site - It'd be good that when any topic has a reply it is bumped to the top of the list? It would save looking up and down to check what discussions had the latest replies. It would save a ton of time and it would make your site more usable. I am not sure if admins are reading these messages, but if you do please consider my proposal.
