Linking to Numbered Headings

You may need to take some care with using numbered headings if you use links to your existing headings. Because of the way that confluence links work, when the heading is changed to add the number, this will change the link address. So, any existing links will need to be updated. If you find that adding numbered headings has broken the existing link, you can turn the headings off and they will work as before.
