Endmyopia:Namespaces

A namespace is a set of pages whose names begin with a particular reserved word recognized by the MediaWiki software (followed by a colon). For example, in the user namespace all titles begin with the prefix User:. In the case of the article (or main) namespace, in which articles appear, the reserved word and colon are absent. (Note: main space articles can optionally include a colon at the beginning with no reserved word, so Article and Article are equivalent. This is usually only necessary for the advanced technique of transcluding a main space article into another page.)
