<p>The basic idea here is that you can easily link to the wikipedia entry for a given topic by putting the [wikipedia]topic[/wikipedia] tag into your post. The tag is replaced by a link that executes the wikipedia search form for that topic.</p>
<p>The plan is to augment this with a mouseover popup containing an excerpt from the wikipedia page.</p>


Wp-Wikipedia-Excerpt

This plugin replaces [wikipedia]topic[/wikipedia] with a wikipedia search link for that term.

<p>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.</p>

<li>Zero configuration</li>
<li>Keeps links that already point to GitHub untouched</li>
