TweetUpdater will send a message to your Twitter account, from you WordPress installation, whenever a new post is published, or when a previously published 
post is updated; as you choose.
The tweet format is flexible, with placeholders for title and URL. URLs can be included from a variety of sources. In addition to full 
post permalinks (standard or friendly urls as selected in your site setup) the following short url services are supported:
Internal services:
<ul>
<li><a href="https://wordpress.org/extend/plugins/le-petite-url/" rel="ugc">la petite url</a> plugin</li>
<li>WordPress Permalink</li>
</ul>
Generic shorteners
<ul>
<li>YOURLS</li>
</ul>
External services:
<ul>
<li>Bit.ly</li>
<li>Stwnsh</li>
<li>TinyURL</li>
</ul>
Posts tweeting can be ommited based on post category, or custom field, or custom field and value pair.
Derived from the original TwitterUpdater, version 3 has been fully rewritten to include OAuth authorisation with Twitter; because basic 
authentication (username & password) has now been deactivated for applications using the Twitter API.
The TwitterUpdater plugin has a great tradition of being updated and improved by anyone who needed it to do something different, and 
as such TweetUpdater is one of a handful of TwitterUpdater forks.
If the short url service you like to use is not included, please see the FAQ on how to add it. If you add a service, let me know and 
I’ll add the code to the next release.

Do you post private content? Are you sending those links to your users with private content access?
WordPress natively send non-logged in users to a 404 (content not found) page when they try to access a post, page, or cpt without rights. This plugin redirects those users to the login page. After successful login the user is then redirected back to the post, page, or cpt they were trying to access.
