Peter,
I like the way you are getting feedback from your students. About three times each semester I ask my students what they want me to stop doing, what they want me to start doing and what they want me to continue to do. Stop, Start, Continue. This is a great way to understand the online structure/class from their point of view and understand what you are doing well and what you can improve upon.
It seems that you have a good communication plan as well. Keep up the good work.
Thanks.
