I'm a proud user of the following open-source FREE software:

Ubuntu Linux
A compleate Linux Operating System. Like Windows(R), only better.

Firefox Web Browser
The Best Internet Web browser out there. Like Internet Explorer, only better.

Thunderbird E-mail Client
A full-featured e-mail client. Like Outlook, only better. (I'm really not using this, cause I'm on Evolution, but if your on Windows, this is a great program)

OpenOffice.org
A compleate Office Suite. Like MSOffice (Word, Excel, Powerpoint), only better.

Drupal
Website management system. This is what I use to run my website.
