The original Z3 theme was designed by DestineDesigns back around 2004-2005 as a PHP-Nuke template. I've been able to recreate this so that todays browsers can view them.
This is not a responsive theme, so do not use this if you are looking for something like that.
The shoutbox is now browser friendly, and no flash is required like the original was.
Please post questions about the use of this template below. Enjoy!
