Hi Kyle,
I think the "Create Connected Access" for a) Activity and b) commenting is bugging.
I have on my site somewhere where everyone can comment on any stream (no connection based)
I have just established the connections and set the modules (which show the stream) to "Same as Global" for "Create Connected Access" and Activity to DISABLED for "Create Connected Access".
User A can only comment below the activity of user b if user A and user B have a connection.
Here it does not matter to what I set the CREATE CONNECTED ACCESS in CB Activity plugin as it does not change anything.
Any solutions?
