27. Should any of the selected types be protected, I will
be asked whether I want to request access

28. If yes, an OAuth request will be sent which Dave
will later be able to approve, deny or ignore

29. ...And Dave’s public activities will
show up in my activities dashboard

30. ...And if Dave approves my request, his
protected activities will show up later

31. More soon at activitystrea.ms
