[Zope] ZopeZoo

In my quest to get to grips with the basics of ZPT I eventually stumbled across ZopeZoo which I found very useful. Looking at it again, there seem to be several variations of the same examples. I used this one:- http://www.plope.com/Books/2_7Edition/SimpleExamples.stx#2-10 but find there are a couple of variations here:- http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/SimpleExamples.s... http://www.zope.org/Members/jwhitener/zopeZoo_2_6 Is there a definitive site for ZopeZoo? And is there a followup anywhere? I found I was getting the hang of it but could have done with a part two to show how to incorporate various divisions such as columns under ZPT. -- John
