Page titles in PGVWiki are composed of two parts: an optional namespace name, and the remainder of the title. For example, this page has the title Help:Namespace, so it is in the Help namespace. A title without a colon, for example, the page, Users Guide, is in the main namespace.
Namespaces among other things allow a separation of content from policy and discussion. We strongly encourage the separation of the pages in PGVWiki into core sets to assist in viewing, navigation and searching. Maintenance of namespaces is also a key feature in maintaining a key aspect of PGVWiki, that is the creation and maintenance of a documentation source for phpGedView.
Note: namespace prefixes should not be confused with prefixes for interwiki linking.
