Posts in Posts will allow you to grab recent posts based on category, tag or just recent posts. Then it will display thoses posts in a list in the post or page you have called the Posts in Posts on. It’s as easy as all you need to do is write a HTML-esq bit of code.
[posts type=”category” name=”Lipsum” limit=”4″ date=”d-m-Y”]
This will then output 4 posts from the category ‘Lipsum’.

This plugin adds a new, sortable, column to the users lists, which shows the date and time they registered.
Primarily useful for single site (which doesn’t show this at all), on Multisite Networks it adds the user’s registration info for all individual sites.

<h3>Privacy Notes</h3>
