Thats a little trickier. 🙂
The first one, the Recent posts one, is from my own custom plugin based on the unanswered plugin but shows recent posts instead.
The second one, the unanswered page, is from the new unanswered plugin available on the plugins page here.
What you would do is get both the Unanswered plugin and the Template tags plugin and put them in your Simple:Press plugins folder and activate both of them.
That will create a page on your site that displays the default unanswered output. It would be at yoursitename/yourfoumname/unanswered I created a custom menu tab on that site so people can find the page. You will probably need to do something similar.
I am using the default settings for the unanswered plugin so the order you see mine is the same as you should get.
I did create some custom CSS for the output though. I spaced the Avatar a little more apart from the text and the borders matched my theme but you may not need to do that.
