Hi, Erik

It is the difference between a class and an instance of that class.

As a simple example, if you want to create a GuestBook using ZClasses 
methodology, you would make a ZClass with a meta_type of 'GuestBook' 
inside the products area.  Then you  would be able to add multiple 
GuestBook objects from the add drop down list everywhere.

The ZClass in the products area would define the behavior of all of your 
GuestBooks, but each individual GuestBook would have its own data.
