Following the discussion on the possible usefulness of a flash tutorial for ZClasses, one might conclude that: "Some people think it is easy to work with ZClasses and some think it is not." This conclusion alone should indicate a need for more or better tutorials on ZClasses. I am sure Dieter is quite right when he says that: "-- but you are using ZClasses because your Zope programming skills are not yet developed enough to implement full blown Zope products." However, I am not sure that every Zope programmer would have the need/desire/ability to become able to develop his/her own Zope products. For these programmers, ZClasses might be an handy option. When it comes to a flash tutorial in general, I see one challenge: The possibility for others to participate in the development/improvement of the tutorial. Within the Zope book everyone can add comments. This constantly serves to improve the book. Such an option in a flash tutorial would contribute to ensure the tutorials further life within the Zope community. Børge
