Be able to create sub-groups
Allow the admin/group creator to create sub-groups to allow different portions of the group to be called upon ie. project managment, administtation, project inspection, billing, company managment
This would be very useful for my use! To take it a step further, how about allowing the Group Files to be shared differently among the sub-groups? When a user is added to the Group, they would be assigned to a sub-group(s) and then can only access the files that have been shared with that group. The Admin sub-group would be able to access all the files.
