Just my two cents:
I think that the mentoring threads should tell you how to do things that a noble would realistically know. How do you post an order to buy food? How do you set up a recurring automated caravan to go buy food from a rural region? How do I found an army, appoint a marshal, and set up a banner for it? What does the "foo" link do?
These are things that a player should know, or that a character would reasonably know how to do, without having to risk clicking the wrong button because the description for it is not clear or the procedure too complex.
