A couple of weeks ago, Andrew Eddie did a great webinar for the GSoC students introducing them to the MVC architecture in Joomla!. As a vehicle for this, he went through the Weblinks component in version 1.6. This component was done as the model for best practices for MVC coding for Joomla!. Along the way, he explains some new things coming in version 1.6, including the new JForm and JQuery classes and some changes in the MVC for 1.6.
