About this plugin
WordPress GPS tries to guide people throughout the WordPress admin jungle. Tell it what you want to do and let it show you the way, with the pretty WP Pointers feature.
Features
This plugin provides an admin panel with a scenario selection. It comes with some default scenarios, which will teach you for example how to:
<ul>
<li>add a new post</li>
<li>add a media</li>
<li>add an user</li>
<li>…</li>
</ul>
Each scenario is defined with capabilities the user must have to play it: if the user doesn’t have these capabilities, the scenario won’t be in the select box.
WordPress GPS is available on Github: https://github.com/lpointet/WordPress-GPS
