LinkMaker lets editors create Wikipedia links without leaving the editor. Link any text to <code>linkmaker</code> (no protocol) and the plugin automatically points the front-end link to the matching article on Wikipedia. It ships with lightweight JavaScript and CSS that only runs on the front-end when needed.
