Andy's Email Users MediaWiki Extension

I looked everywhere for a solution (extension) to send an email to every user of my Wiki, but never could find one. The closest I could find was an extension to email a page from the Wiki to a user. So what I did was modify it to my liking. I now present you with an extension that will allow you to send a mass email to users or groups within your Wiki (you can also send to users outside of your Wiki). Please note: that this extension uses phpmailer and is currently configured to use sendmail. If you don't use sendmail or Linux/Unix you will have to reconfigure class.phpmailer.php (included). For more help on this, please visit their website. Also note that I wrote this extension for MW 1.11.0 but it should work for earlier versions (at least back to 1.8.0). Now, on to the extension.

TO INSTALL:

Download the zip (below) and extract it to the extensions folder of your MediaWiki installation (the EmailUsers folder should be in your extensions folder).
Add the following line near the end of your LocalSettings.php file:
include ("$IP/extensions/EmailUsers/EmailUsers.php");
Browse to your Special Pages and look under "Restricted Special Pages" (you must be a sysop to view this page, by default) for "Email Users".

CONFIGURATION:

There are a couple variables you can change if you'd like:

Change
$wgEmailUsersGroup = 'sysop';
to another group to change who can send emails.
Change
$wgEmailUsersAllowAllUsers = 'true';
to prevent sending to all users of the Wiki (the "user" group).

TODO: (if you can help, contact me)

Make the "To" field a "BCC" field (this isn't important for me right now, as my Wiki is private) to hide the names of recipients.
Cleanup remaining code from EmailArticle.php (original extension).
Log sends to a log.
Rewrite to use built-in mail class instead of phpmailer.

BUGS:

Shows each email address twice (don't worry, it only sends it once).

If you like it, or have any problems, please let me know. Enjoy!!
