Thanks Chris, that works great. I turned editing on and added activities/etc to the top block as you mentioned.
For your developers here is another idea: could restrictions/completion tracking be used to allow/disallow access to commenting/posting?
It would be good if students had to complete an activity (which must be marked completed via restrictions/completion tracking) which then allowed them to post/like/comment. This is helpful as we could make our students read and sign a digital citizenship policy before they are allowed to post, etc.
Thanks for your ongoing work,
Jason
