if the knowledge is in my head, how come that wolfgang can answer most questions (and if he couldn't we'd have a real problem as at least i have not more time)

Actually, I don't need so much documentation (well, it's never enough indeed), I'd say I need a tutorial to be able to know how to get documentation.

This is just my experience, for what it worth: I always find very good recipes, and fast help by this wonderful list on specific topics, but I don't feel to be able to really generalize my knowledge.
