Get an overview of how active your users has been during a specified time period. This plugin will list all the users, 
the number of posts/pages they have created and when their latest post was created.
You can sort all the columns, filter by post type and search for a specific user name.

User Activity

List number of posts per user. You can limit the search by date, post type and user name.

Sometimes when you divide up your WordPress content into categories it all ends up in sub-categories of one or two main categories that don’t have any content themselves.
With the widget you can add a list of sub-categories even if the parent doesn’t have posts.
You can display and filter sub-categories in various ways:
<ul>
<li>Use the parent category as the widget title</li>
<li>Show post counts in bracket next to the name</li>
<li>Hide empty sub-categories</li>
<li>Add a link to the parent category to the widget title</li>
<li>Show the full sub-category tree so it include sub-sub categories and so on as well</li>
<li>Display the list as dropdown rather than as links</li>
<li>Use the first category of the current post as the parent</li>
<li>Exclude one or more sub-categories from the list</li>
<li>List the categories in reverse order</li>
</ul>

Sub Categories Widget

This Widget lists the sub-categories for a given category.
