 It is outdated, not maintained and frankly there are better plugins to use.

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 for WordPress MU is really simple. It allows site administrators to send a (plain text) to all users. You can type in the subject and text for the email, and it will try to send it to all user email addresses in the database.
That’s pretty much it.
There are two small additional features with this plugin. Firstly if any emails fail to be sent the failing email addresses will be shown in a list, so you can decide what to do. Secondly there is a “Test” checkbox, which when checked will only send the newsletter to the site admin email address.
If you have a lot of users this plugin may take a long while to run, as it sends a separate email for each user. There is some reasoning behind that: in the future I may write in some special codes that you can use in your emails that will insert the users email address (so they can unsubscribe, for instance), a link to their wp-admin folder, and more user-specific data. That stuff is pretty much impossible to do if you use BCC to send one email to multiple people.

Sitewide Newsletters

Sitewide Newsletters is a Wordpress MU plugin that allows site administrators to send an email message to all users.
