Now I think we all agree going through forum and forum finding something to relate to is hard. So you should add a "New Posts" option. Basically it will tell you all the new posts people have created since the last time you visited the site. That way topics get known more and get alot more replies! Keep up the awesome forum -Rocky.
I believe that is an option already, look in the nav bar where it says "What's New?", is that what you are looking for? I would suggest a New Posts sidebar though.
Yeah, It's a basic forum Feature. Click the What's New Button on the top, will take you to all thread with new posts In it you haven't seen Or new stuff since your last visit
