Example page
OK. You discovered that there is also a page functionality. But what is the difference between a page and a post?
The difference
A page is intended for "timeless" objects like your imprint, the privacy-policy, the about page, your FAQ's and similar stuff. Posts appear in the RSS feed, pages do not. Posts can be assigned to a category, pages cannot. Posts can be searched by the visitor, pages cannot. Besides this, there is not much more difference between a post and a page currently.
