Custom Page User Items provide an easy way to add custom content to your site. They can be used for any content that is not supplied via your TMG database or one of the other User Item types. Some users add Custom Pages to provide surname histories or place histories, others use them to describe the history of their research project, and there are many other uses.
This page was added using a Custom Page User Item, and as you can see it follows the overall look of the site and includes the header, footer, navigation menus, and other elements of site pages. You provide the primary content, and Second Site supplies the rest of the page.
Custom Pages are also used to create lists of other items, including other pages.
The text above is in the Main Content field of the Custom Page Explanation User Item.
