<p>There are times when you’d like to have a certain type of post appear in a widget for use in your sidebar or (in some themes) your header or footer.</p>
<p>I used this to display a random senryu on each page, but it will work equally well for any group of reasonably small posts.</p>
<p>There is the option to include the title of the post, the title of the widget, both titles, or neither.</p>
<p>If you want you can add a bunch of widgets, each showing up to five random posts from a different category.</p>


Random One Cat Widget

This Widget shows up to five random posts from a given category

<p>Post Date Randomizer allows you to bulk change the publication dates of your content to random dates within a specific time range you define. You can choose to randomize dates for published posts, pages, products, custom post, approved comments, or both.</p>
<p>It comes with a simple but powerful settings page (“Date Randomizer” in the admin menu) where you can:</p>
<ul>
<li>Select whether to randomize posts, comments, or both.</li>
<li>Set the start and end dates for the randomization range (past or future).</li>
<li>For posts, choose the specific post type to affect (auto-detects public post types like posts, pages, products, etc.).</li>
<li>For posts, optionally set the “Last Modified” date to match the new random “Published” date.</li>
</ul>
<p>It supports any date range. Posts with dates randomized to the future will be automatically scheduled for publication. Comment dates are simply updated to the random date within the selected range.</p>
