How do I create a new page on my web site?
If depends what you mean by a page. The areas within an Insight web site are generated by creating new group folders, these group folders are displayed on the site navigation menu provided they have a group homepage article published within them. Each group folder can contain several articles, and each article will normally represent a page on your web site.
If what you require is to create a new item on the navigation menu then you'll need to create a group and publish an article within it. If you already have a group within your site structure to locate your page then you can simply create an article. A link to your article will be needed to access it, but this will normally be generated automatically by the article list component.
