To accomplish this we were given the option to do one of these tasks:
1) Categorizing the posts and putting them on sidebar or in drop down menu
2) Creating a "Popular Post" page or widget
3) Cross linking between posts
4) Creating a 'start here' page that lists our most helpful posts
I have already categorized my posts and placed them on sidebar.
I have popular post widget and I usually do cross linking between posts. So this was easy as I have already done it :)
