If your classroom looks a bit different today, it may be because I'm working on a solution to a log-on problem reported by one student (she is able to log in to her account but unable to enter the classroom with her iPad).
If you encounter this problem (or another one), please email me.
I'm considering another platform change that would (I hope) improve things for students using mobile devices to access course material. Will keep you posted. In the meantime, thanks for your patience!
