How to add the "Read More" Tag
I didn't like the fact that if you had a large post that it went on forever so I used the "Page Break" function on the tool bar to make the post a more suitable size and more pleasing to the eye.
See the picture above, the yellow highlighted area of the tool bar is where you can add this tag, right next to the "HTML" button. Hoover over it and it will show a popup of the "Insert Page Break". This will add the more tag so that you don't have a post that goes on forever.
Hope this helps others.
