all killer.  no filler.

To install phpList via QuickInstall:

1.Log into cPanel.
2.In the Software/Services section, click the QuickInstall icon.
3.In the left menu, under Mail Software, click phpList.
4.Click Continue.
5.Select the domain on which you’d like phpList installed.
6.Enter the admin email, installation name and admin username.
7.Click Install Now.
8.Once the installation is complete, you can access your admin area by going to:
http://yourdomain.com/admin/index.php
Be sure to replace yourdomain.com with the actual domain on which you installed phpList.
ProTip: Avoid sending to multiple addresses using the CC field. Everyone will be able to see each other’s email address.

You can always send to extra addresses using BCC, but this can be a hassle when you often have new people to email.
