Creating a MediaWiki page
Creating a MediaWiki page is somewhat similar to the page creation process for a normal article pages in a wiki. The primary differences is that MediaWiki namespace pages are part of the actual software that controls the MediaWiki installation and as a result, you will need the "Edit the user interface" right to edit them. Typically a MediaWiki namespace page will be titled something like "MediaWiki:Mainpage", or "MediaWiki:Sidebar".
In order to access (or edit/create) a MediaWiki namespace page, type in the full and exact name (including the MediaWiki:-namespace prefix) into the Search field of your wiki. Submit the search. If you're not getting any results create the page by clicking on "Create the page MediaWiki:Example on this wiki!"
The very first time an admin attempts to access a (properly named) MediaWiki:-page, the software will do one of two things:
- It will offer the user the option to creating the page being asked for (you see the editor and can start typing and then Save the page)
- Or, it shows the default value of this option. Click "Edit" or "Create" in the navigation bar, then alter to meet to your customization requirements.
