Battlestar Wiki:Tutorial (Namespaces)
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
Current list of namespaces
This is the current list of active namespaces throughout all languages. The "Media Wiki" as a custom set of namespaces, but there is only one version like it. Each namespace also has its own talk namespace, which is formed by appending "talk" to the namespace name (e.g. "Template" has "Template talk").
User pages and user talk pages
If you want to share information about yourself, the place to put it is your user page. If other users want to communicate with you, they will leave a message on your user talk page.
Some other areas
Pages in the Battlestar Wiki namespace (also known as the "Project namespace") provide information about Battlestar Wiki and how to use it. The MediaWiki namespace contains interface texts such as link labels (What links here, etc.) and server messages. All the pages in both these areas also have corresponding talk pages (in the Battlestar Wiki talk and MediaWiki talk namespaces respectively).
Content written in a Template page will be displayed in articles that contain the corresponding template reference. Take a look at BW:TEM project to see what templates have already been created. You can use the corresponding tags in articles. You can also create new templates.
