There are two types of pages in vBulletin. System Pages and Custom Pages. System pages cannot be removed and may contain modules (content blocks) that are required for that page. However, System Pages can be edited and have optional modules added or removed to customize the page. You can also create Custom Pages. These can be added and deleted and may contain any number of modules. You can access your custom pages by clicking on the Pages link.
This is a list of all custom pages that you or other administrators have created on the site. Clicking on the page link will take you to that page.
This shows a list of all channel (Forums, Article Sections, Blogs, Social Groups) pages created on the site. Clicking on the page link will take you that page.
When you create a custom page, a new template is created along with it. When you delete the page, the template isn’t deleted automatically because it may have been used multiple times. Any custom page templates that aren’t being used by current pages will be listed here. You can clean up your template list by deleting unused templates.
