This.Completed (except as noted below).
And this.I have no idea what question 13 was supposed to mean.
Questions 14 & 15 are so broad and open ended you simply won't get any statically useful information from them.
Also, the Question on D&D Insider is not going to help you, since DDI has many features that will determine how a person answers that question - and you have no idea which feature is driving the decision.
