TJ asked for this.  He wanted to be able to set where the preview break occurred.  To insert a page break, first write your entire post.  Put the cursor at the beginning of  the paragraph you would like the break to begin and click.  Everything below this paragraph will be removed from the preview.

Now, click on the "Templates" button

A new window will open asking you to select a template.  Click on the dropdown menu and then click "Insert preview break."

Finally, click "Insert" and an image will appear showing you where the page break will be inserted.  Everything below this will be deleted from the preview!

Great, let me know if anyone has any issues!

Fixed, let me know if anything like that happens again. Or if stuff starts disappearing :P

Wonkiness was because you inserted it on a paragraph that started with a bold character and the text editor did some goofy things that made my coding hallmarks disappear :(  I'll have to find a way around this special case scenario :P
