Q. Why can't I find the content I just submitted?
A. The search index (used for searching in content) updates once every hour. (See also search/updates)
Q. I cannot find the page i just created, where did it go?
A. To add a page at a specific location in the menu, you have to say where you want it to appear before you submit the page: 'Startpage', 'Drafts' or in the menu. When no location is specified, the page created is placed on the frontpage.
If you accidentally placed content on the frontpage, and want to put it in the menu, click the title of the 'misplaced' content, scroll down in the content edit form, and adjust the 'Placement of content' to the place where you want the content to appear. Now press submit; the content will reappear on the intended place.
