What are sections and data-types?
Tank allows you to express yourself through the following data-types:
A page section is no different from another page except that it’s accessible at the root of your site. Tank allows for the creation of different types of pages: splash pages, contact pages and regular pages too. Pages are nestable, which means you can attach a page to a page (to a page).
A post section is different in that you can create multiple posts within a post section, and these posts are ordered chronologically within the relevant post section.
In a photo section you are creating multiple albums, and in these albums you house photos.
