Expires a user’s access to a site after a specified number of days. It uses the user registered date/time and an admin configured number of days to determine when to expire the users access. The administrator can restore a user’s access from the user’s profile page.
There is a filter available for developers to hook into and alter the expiration date of a specific user on the fly during authentication. The filter uae_expiration_date passes the current expiration date and the WP_User object.

User Access Expiration

A user's access to a site is disabled after a specified number of days. The admin can set the number of days since registration to deny access.

This plugin is now part of the free plugin <a href="https://wordpress.org/plugins/tietools-automatic-maintenance-kit/" title="TIEtools" rel="ugc">TIEtools</a>, which also includes duplicate post control and server log file removal.
Simple post expiration plugin. Expires posts based on a variety of criteria, including category and post status options.
<ul>
<li>Expires published, draft, pending and private posts on demand.</li>
<li>Includes or excludes user-defined list of categories.</li>
<li>Moves all expired posts to the Trash.</li>
<li>Notifies post author, site admin and others of post expiry on demand.</li>
<li>Permanent post deletion is handled by WP’s built-in Trash removal.</li>
<li>Completely automated by wp-cron once options are set.</li>
</ul>
Currently, the plugin offers four cumulative expiration methods:
<ol>
<li>Expire posts based on their age (e.g. expire posts created more than 90 days ago).</li>
<li>Retain a given number of posts and expire all others (e.g. keep the latest 1,500 posts).</li>
<li>Detect the BAW Post Views Count plugin and expire posts based on a combination of post age and number of views (e.g. expire all posts over 45 days old which have fewer than 100 views).</li>
<li>Detect the WTI Like Post plugin and expire posts based on a combination of post age and total number of likes (e.g. expire all posts over 90 days old which have fewer than 10 likes).</li>
</ol>
Each expiration check is run separately and in the order listed above, so you can build quite complex expiration structures to catch a variety of criteria.
Post status choices apply to all expiration methods. The user-defined category filters can be switched on or off for each method.
