MediaWiki Editing Basics
The fundamentals of using MediaWiki can be found over at the MediaWiki site:


 * Formatting Markup and Layout
 * Using Tables
 * Internal and External Links
 * Using Images
 * Managing Files (including Images)
 * Primary Help Pages from MediaWiki.org

You can search for external links matching a certain protocol with Special:LinkSearch. There doesn't seem an easy way to get at all of them at once, but you can use,   and the like to return all links for a given TLD.

Redirect one page to another
To redirect an existing page to another page, use the following syntax as the first line of the page to be redirected:


 * 1) REDIRECTPage to redirect to

=+= Transclude one page inside another ==+

In addition to MediaWiki, this wiki also uses Semantic MediaWiki, which (per Stack Overflow) allows you to do clever stuff like insert links to all pages in a given category as a bulleted list, like so:

This yields:
