Hi Martin. You can edit over existing chapters using the Edit button, but that won't notify everyone that there's a new chapter. Instead, use the Add Chapter button. Then, instead of given a new chapter number, use the previous chapter number and change the version number to two. Once you hit the publish tab in the Add Chapter wizard, go ahead and publish the new chapter AND make the old chapter inactive. Making it inactive ensures that only you can see it, and it retains all of the old reviews on that chapter, which also only you can see. If you're totally done with the old chapter, then you can delete it, which also deletes the reviews associated with that chapter. If you don't make the old chapter inactive, nor delete it, then both chapters will appear once you publish
Clear as mud? I hope I got it right.
