This plugin is only supported on PHP 5.2 or greater.
 
MUWidgets adds widgets to extend the standard WordPress widgets to be able to run as if on another site on the Multisite installation.
You now have a number of new widgets prefixed with the word ‘Site’ that operate the same as the standard WordPress plugins, just with the addition of a ‘Site’ option in the setup. 
You are able to select any Site on the Multisite installation that you have administration access to. 
 Just select the site and click ‘save’ now the widget is operating as if it was on the other site, enabling you to display for example the blogroll or recent posts from the main blog.

Developed for WordPress MU, this plugin gives you the ability to set custom description and keywords meta tags in the head area of your site.
The plugin is helpful because it gives the site admin the ability to set keywords and description for every page on every blog (site wide) and then it allows each individual blog admin to set their own description and keywords. The plugin then combines them into one before inserting the result into the head of your website.
This is my first plugin for WPMU. Please let me know if you find anything that I should be doing differently.
To adjust the site wide keywords and description: 
* Sign in as a site administrator 
* Navigate to the Site Admin page 
* Click on the Site MetaTags link.
To adjust the keywords and description for a single blog: 
* Login as the blog administrator 
* Navigate to the settings tab in the backend. 
* Click on the MetaTags link
