The ONL course

ONL course has a website where all course material is published. In addition, we use Google+ group rooms.
There is a group room for the entire course, and each study group has its group room.
I'm a beginner in Google+
For me, it became overwhelming at course start that there are so many messages sent from the rooms. I had to turn off notifications from the big group room for the first day so I would not drown. However, I'm missing out on things I should have enjoyed seeing. I guess it's easier if you're used to Google+ groups
If I were to use Goggle + in my own teaching, I would have had to use a teacher account so I could log out after work.
