I don't want to start another thread with almost the same question.
I've added a new group lets say "Flight operations" and checked EDIT_DOWNLOADS, EDIT_FLEET, EDIT_SCHEDULES, MODERATE_PIREPS, VIEW_FINANCES. After this I went to the profile page of the desired user and added him to the Flight operations group.
The question is, how can the user (staff member) access the checked sections? to edit downloads, edit fleet, edit schedules, etc?
