Yep, a discussion thread held open by a tutorial creator - we could use the example of the EDB Guide or the Palm Forests on the Battlemap tutorial/discussion as examples - are great ways of learning (often together!). It is something that is usually beneficial to the "tutor" too as he wants to understand the matter, get a certain result, or even just get the material up and polished.

In the final analysis, good modders need the mettle to become so and all the tutors in the world will not cure laziness, vast incomprehensions of workloads, unfounded idealism, lack of commitment, lack of aptitude for modding, etc., in the would-be modder. That "mettle" will be manifested in the person being largely self-taught.
