WordPress generates shortlinks for your posts and pages. By default it uses the <code>?p=</code> with the post ID added to it, but if you have a rather long domain name this isn’t very useful. If you use <a href="http://bit.ly" rel="nofollow ugc">Bit.ly</a>, this plugin will help you replace the shortlink WordPress generates with a proper Bit.ly shortlink.
This plugin uses the latest Bit.ly OAuth 2 draft specification API instead of its deprecated V3 API and enables you to use generic access token to automatically enable Bit.ly shortlinks in your entire multisite network without the need for each site user to have to tinker with any settings or authentication configurations.
