I find that crossing a palm with silver earns instant forgiveness.
Questions are fine, it shows I need to elaborate in the help file more to try to ease the confusion. It is always difficult to find a balance in help files though. If I completely spelled everything out in explicit detail so that someone who had never seen an epub before could understand, then (a) it would take me days to write and (b) it would be enormously long, which would put a lot of people off reading it.
Heck I hate reading help files myself. In all but the most technical of areas it is frequently a sign that you have failed as an interface developer if your users are forced to go looking in the help. This however is for the most part a very technical plugin with some obscure options that I guarantee the majority of users could not otherwise explain what they do or why they might use them.
As the report card says, "must try harder".
