I am just 21 years old now, and I remember like it was yesterday, my mom telling me about what should and should not be done on the internet. I knew I didn't want it taken from me, so I did what she asked. (Also the computer was in a public room, so it would have been hard for me to do anything anyway) I don't know how your computer is set up, but if it's a laptop, you should have her in a public area of the house to have her internet time, and also you can password protect, so that she cannot even turn the computer on if you are not there. IF you have a desktop and it's in a "computer room" or office, have her leave the door open so she is in view anytime you want to take a peak. I think it's great that she enjoys writing and may even do it well. You don't want to discourage something she enjoys and with a GPA like that (I wasn't a star student), I would assume she has a good head on her shoulders. Give her the benifit of the doubt.
