Access to edit/hide/delete functionality in discussions in group bulletin boards dependent on group privileges. Breadcrumbs include link back to all grups list when discussion was accessed via 'Groups' link. For both bulletin boards and discussion attached to resources, filtered display of posts can now be based on group affiliation. For users with mdg or vcg privileges in the course, selection is from all groups, for others selection is from user's own active groups.
