Of course:

def initialize(registrar):
  ...
  registrar.registerClass(
      VolunteerUserFolder,
      permission = 'Add Volunteer Objects',
      icon = "icons/vuf.png",
      constructors = (manage_addVolunteerUserFolder,),
      )

(same effect with classes which have two constructors---(manage_addX,
manage_addXForm) )

I'm still not clear where the attributes for

  context.manage_addProduct['Volunteer']

come from -- if I added .foo() to the end of that, where would Zope
look for 'foo'?

Thanks for the thoughts so far..
