Admin Forum:Changing the Chat Widget text

As the title shows, I'm trying to change the text in the chat widget on the right side of pages, i.e. where it says "Community Central" for the chat widget here.

Is the correct MediaWiki page for this MediaWiki:Chat-headline ? If so, is there any specific format that must be used for this system message? And is there any way to force the interface to update so I can see the effects of these changes? --Destruction Matter 00:27, June 19, 2012 (UTC)
