I've done a few things through OTEN. Its pretty good, but the only problem was that alot of my course notes were on the website and I get distrcted easily so downloading my notes always took much longer than it needed to! You can opt to get them to mail you the notes, but I asked for the online version. Anyhow, it was great to be able to do my work in my own time and not have to take time off work to attend classes and exams.
