Sorry, but typing out answers to a list of questions can be very time consuming. If you have a specific question for someone in the directory you may ask her, but there may be times when she is unable to answer you. Also, the purpose of a class project is generally for you to speak with an engineer. There are engineers in the directory who have indicated that they would be willing to conduct a student interview. If you find one that you would like to know more about, please send her a request for an interview, but aviod just sending a long list of questions especially if you only have a couple of days to complete your assignment.
