  So, 'Challenge.py' defines a new PortalContent class called
'Challenge', and the Challenge Wizard is supposed to create instances
of this new class, correct?

  Before you can instantiate new PortalContent classes, they have to
be registered with the PTK.  See the bottom of NewsItem:

from Products.PTKBase.register import registerPortalContent

  This code is executed when PTKBase's __init__.py module imports
NewsItem.  You will need similar registration code in your
Challenge.py module.  For it to get executed, you will need to import
your Challenge.py module from the __init__.py module.

  There is information about registration on the PTK Wiki.

  Once this is done, you can name the constructor you selected when
registering the class in the Wizard's Properties view.

  This still leaves you with a problem-- you've forked the PTK, and
you may have trouble tracking changes.  Rather than place your
Challenge code in the PTKBase Product, you should create your own
Product to place it in.  So long as you register the class as above,
it will be found by the PTK.
