bbRedirector makes it easy to redirect a page to another location using absolute urls from within WordPress. 
No mod_rewrite nor .htaccess is needed. You just create a page, add a specific customfield and choose the 
redirect template included with this plugin. It even allows you to set the required http status code (302 or 301). 
You can also set a default sitewide redirection or setup your own custom redirection.
The included templates should give you an easy start using this plugin.

This plugin creates site-wide topics. Each blog can be identified as belonging to a single topic. Blog owners can select a topic for their blog at creation time, and through a menu under settings. Blog owners can also choose whether or not to include their content in any site-wide aggregated content via the Blog Topics Settings menu.
Site Admins can set up the site-wide topics, select a “featured topic,” and manage blog’s topic settings through the Site Admin -> Blogs -> Edit menu.
This plugin comes with 5 optional widgets (in the widgets subdirectory).
<ol>
<li>BT – Topic Name – displays the name of the topic of the current blog.</li>
<li>BT – Related Blogs – displays a linked list of other blogs in the same topic.</li>
<li>BT – Related Posts – displays the title of the N most recent posts in the same topic as the current blog.</li>
<li>BT – Featured Topic w/Posts – displays the N most recent posts from the “featured” topic.</li>
<li>BT – Topics w/Posts – displays the N most recent posts from each topic, with the option of excluding selected topics.</li>
</ol>
Some of the widgets rely on theme code for topic listing pages and site listing pages, referred to as “portal links.” All portal links can be turned on and off in the widgets. This plugin comes with a sample theme to help you learn how to modify your own theme to incorporate the portal elements.
