Content types are building blocks that make up your webpages. Webpages are created by creating sections/folders in T4, and content types are added to those sections/folders to make up the webpages.
On some sections, it is possible to use multiple content types on one page.
The content types you can see are specific to your login type. Contact the Web Team if you need content to be created using a content type you don't have access to.
