Forum:Announcements?

Hello! I really like this Wiki, and i own my own one, that's about my prototype project. I'm trying to make my Wiki better, and I wanted to learn how to create that announcement comment that's on top of each article. Right now it's a countdown to Christmas. All I need to know is what to name it (MediaWiki:, Template: or something like that), and then the name of the page itself. Thanks! -- Oramis Eram Hic  15:35, December 22, 2009 (UTC)
