Extension:NewsTicker

The NewsTicker extension adds a special page to show a news ticker at the bottom of any desired page. The special page controls what news are shown on what pages, as well as the width and height of the news ticker on each page.

To use the special page, the "newsticker" right is needed, but the extension grants it to all admins by default.

The data set through the special page is saved as JSON at MediaWiki:News.json, so no database changes are required.

Usage
Once installed, go to Special:NewsTicker and set the news you want to show on each page.

The default style of the news ticker is ultra minimalist, and can be easily changed from MediaWiki:Common.css
