Hi! In my own Wiki (based on MediaWiki engine), in LocalSettings.php config file I created new custom namespace with the name of "Foo":
$wgExtraNamespaces = "Foo";
I have a question. How do I get to create a new tab with the same name "Foo"? As a result, the tabs bar would look like this: "Article", "Discussion" and the "Foo". As for example, the additional tab in the Wiktionary is a "Citation" tab.
In advance thank you very much for the help.
