Feedback

Hi everybody,

I'm using the feedback module in my site. I have about a thousand students who recently applied a written examination after completing a course. I need their feedback so, I'm asking them to answer a survey in the feedback module and after that, they would be able to see their grades (yes, it is obligatory to answer the survey in order to get the grades!). I am wondering if there's a possibility to modify the feedback module in a way that after completing a survey, it sends an e-mail to the student (instead of sending a notification to the teacher or administrator) containing an attached PDF document with his/her grades?

If there's a possibility of achieving this, I'd appreciate any hints you could provide (I understand some PHP). Thanks in advance!
