Help:Pages
Technically there are three different kinds of pages:
- (Content) Pages which are initially empty and can be filled and edited.
- Discussion pages attached to them which are called Talk Page and can be edited like the above.
- Special Pages which provide different functions like Change email address. They can not be edited and do not have a talk page attached.
This help page explains the different kind of content pages.
Name Spaces & Categories
This page is in the name space 'Help' and in the Category:Help. You can see its name space in the tab at the top left of this page, it reads: "Help page". You can see in which category or categories (if any) a page is at the grey box at the bottom of every page. It reads: "Category: Help".
Our main name space got no name, therefore all those pages show simply "Page" in the tab: WikiIndex. You can use the advanced search form Special:Search to 'include in the search' or 'exclude from the search' any given name space while searching pages by title or content (text is written in the page).
If You go to our root category All or to the complete lists of categories Special:Categories you can browse pages hierarchically means according to their place in the category structure, not by content.
