A WordPress developer. I maintain 3 Centos, Apache servers using Cpanel with over 200 WordPress websites.
I'm learning Ubuntu and have it installed on my desktop. I want to be able to teach others how to use Ubuntu as an OS.
When I'm comfortable enough with Ubuntu I want to switch the server OS to it.
I have been using Open Source software for 15 years.
I've worked with the following open source :
WordPress
OsCommerce
Zencart
Joomla
PHPlist
