The "Featured" listings, which are highlighted in yellow and remain at the top of any category are a Premium Member benefit.  Each Premium account has the ability to "Feature" six firearms live on the site at one time.  If you list a firearm and also utilize the 2nd category placement it still counts as only one use of the "Feature".   In the add listing page next to the “Title” box there is a small box that you need to check, which says “Make Listing Featured”, check this box.  Once your account has placed the six firearms utilizing the featured listings, this box will disappear.  Should you sell one of your featured listings and remove it, and then wish to feature an existing listing, you may go to your “Sellers Page” and choose edit for the listing, check the box for "feature this listing" and then click “Update Listing”.  You may also utilize the edit page to change which firearms are "Featured".  If you wish to pull one off of being "Featured" simply uncheck the box which will allow you to "Feature" one of your other firearms listed.
