Extension:NewsTicker

The NewsTicker extension adds a magic word  to insert news tickers into wiki pages. The style and content of the news tickers, as well as the allowed pages where it can be displayed, are configured from a special page at Special:NewsTicker.

To use the special page, the "newsticker" right is needed, which is granted 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. Then go to each page and add the  magic word in the precise location where you want to display the news ticker.

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