MediaWiki talk:Talk

What exactly is this page? It's a page with "talk" in its title, but it's not a talk page? Does it serve any purpose other than making my head hurt? (I'm going to assume it's testing something or other; I might be able to guess what, but it's probably none of my concern. :P) --Emufarmers 23:27, 18 April 2006 (PDT)
 * It contains the string for "discuss this page" at the top of your screen - editing it will cause the "discuss this page" bit to change on all wiki pages. -Lizthegrey 01:51, 19 April 2006 (PDT)
 * Ah, I get it. I'll assume that's the case for all the protected pages I see with random little bits of gobbledygook. :) --Emufarmers 01:58, 19 April 2006 (PDT)
 * Anything in the Mediawiki namespace is part of the wiki software. --Guppymomma 05:36, 19 April 2006 (PDT)
