See also: Wikitravel:Namespace index
The MediaWiki software used by Wikitravel lets us split up the site into multiple namespaces. With namespaces, each page is explicitly tagged to show what it's used for and where it fits in the site.
To make a link to an article in a namespace, you use the namespace name as a prefix to the article title, separated by a colon. For example, [[Wikitravel:Help]] is a link to the "Help" article in the "Wikitravel" namespace. See Wiki markup for more information on making links with namespaces.
The namespaces currently in use for Wikitravel are the following:
It usually makes a lot of sense to link from other namespace into the main namespace, but not the other way around.
