It's easy to create related page links at the bottom of content pages. Here's how:

When you create or edit a content page, one of the options on the page is a box named 'related pages'. This box contains a list of the previous 1000 pages posted to your site.

You can select as many of these pages as you like to be shown as 'related pages' on the content page you are adding or editing.

To show related pages, hold down the ctrl key, and then click on the pages you want included as related pages. Below is an example of what this can look like.
