1. Possible to update through mobile/email/iphone-app/phone-call, do u have plans to do so anytime soon ?
2. * Could you be more clear about your intentions on offering the student account for free.
3. Is all my information exportable (also as spreadsheets etc.), do u have that option right now/plan to do so soon?
4. Possible to check grades with a classmate, but not a teacher(privacy features etc.) and compare ?
5. * Possible to arrange the courses according to semesters/years ?
Also perhaps, a facebook/goog/openid/ etc. login should help convincing students to signup.
