Who uses it? Tell me about it. How much work is it for the teacher? How much work is it for the student? Does the purchase license follow the student (e.g. can it be used by the student in multiple classes?) or does it follow the teacher (e.g. the teacher gets enough licenses for her students?) What does it do besides give a score/rating for plagiarism ... does it offer any type of editing? help to students? What do you NOT like about it? What do you LOVE about it?
