This is a good way to index our posts that are recurring. I came up with the idea when I wanted to show Khoa all our "romance books" pictures but I didn't know where they were. Now all you have to do is click the "novels" label! I might have missed labeling some posts, so if you want you can go check our past posts, hit the edit button, and add labels. And from now on you can label your new posts.
This picture shows you where the label box is. And the pre-existing labels will pop up when you enter the first letter, so all you have to do is click the box that pops up.
