This plugin creates and maintains one or multiple hierarchies of blogs in the WPMS network. Options screens appear in network admin dashboard. The blogs hierarchy can be used for several purposes such as:
<ol>
<li>consolidate posts (or latest posts) from descendant blogs only</li>
<li>display a list of descendant blogs or even a tree of blogs from any node</li>
</ol>
Other features
<ol>
<li>Hierarchy cannot loop (cannot set as parent one of the descendants or itself)</li>
<li>The main site (blog_id 1) cannot have a parent</li>
<li>Individual blogs may be taken out of hierarchy</li>
<li>Multiple independent hierarchies may be created 
Limitations: this plugin is not optimized for large installations. More than 50 blogs can be hard to manage.</li>

This plugin will display the name of the WordPress Template in use for the current page at the bottom of the page. It will only show in the front end when you are logged in. Just deactivate the plugin when you find which template you need to adjust.
<h3>Usage</h3>
Just activate the plugin and when logged in as an Admin look at the front end view of a WordPress theme, look at the bottom of the page to see which WordPress template the current theme is using.
