Did you ever manage to figure this out? I’ve looked through both the WP and BP Codices and I had no luck in tracking down the documentation for the bpdev_set_email_notifications_preference function. I reached out to another person on a different thread who seemed to have some insight into this matter. I’ll let you know if, when and what I hear back. I’m interested in figuring this out b/c as of the time of this posting there are two additional group options that I need to default to “off.” If you’ve figured out how to handle your #5 option, I would greatly appreciate you sharing your findings with me.
