{{main|MediaWiki#Namespaces}}

Main articles and most of their associated subpages are in what is called the '''Main namespace'''. We say "most" because, technically speaking, any article's talk page is in the '''Talk space''' and the metadata template is in the '''Template space'''. User pages for individual authors and their associated talk pages and personal sandboxes (if any) are all in what is called the '''Userspace''', and Citizendium's policy and instruction pages (this one, for instance) are in the '''CZ namespace'''. Except for the main namespace, all namespaces are characterized by the page titles being preceded with a prefix (e.g. "Talk" or "CZ") and a [[colon (punctuation)|colon]].

==Our namespaces==

You can use the drop-down menu on [[Special:Allpages]] to list the active namespaces on Citizendium. The table below lists the namespaces on Citizendium.

(Note that the number of pages in each namespace may not be displayed on all {{MW||MediaWiki}} projects, because this counting feature may be disabled): on this Wiki, per-namespace page counting is currently {{#ifeq:{{urlencode:{{PAGESINNS:0}}}}|{{urlencode:[[:{{ns:Template}}:PAGESINNS:0]]}}|disabled|available}}.)

|{{#ifeq:{{PAGESINNS:0}}|[[:{{ns:Template}}:PAGESINNS:0]]|''disabled''|{{PAGESINNS:0}}}}

|Registered users (list: [[Special:Listusers]]) have a user homepage User:''username'' (linked to by the system from user names in {{WM|Help:Edit_summary#Places_where_the_edit_summary_appears|lists of edits}}, e.g. on {{WM|Help:Page_history|page histories}}, and from signatures on talk pages); this and {{WM|Help:Link#Subpage_feature|subpages}} of it can be used to present oneself, for project-related bookmarks, and for drafts, tests, and other working material. One can put here material to give oneself one-step access to it from any page in the same project, and one can put here links to give oneself two-step access to the link targets from any page in the same project as the user page.
