Extension:ViewWikitext

The ViewWikitext extension lets you view the raw wikitext of a page by a special page. This could be useful if, for instance, you wanted to have the Internet Archiver archive all the wikitext on your wiki. This extension goes well with Extension:OneColumnAllPages.

Usage
Special:ViewWikitext/page_name will give you the wikitext for page_name.

Adding to the sidebar
Now when people view your wiki pages at the Internet Archive, they'll have a link they can click on to see the wikitext.
 * Go to MediaWiki:Sidebar on your wiki. Under * navigation, add ** viewwikitext-url|viewwikitext.
