With a school our size and no other option offered to communicate to a certain group, we have assigned to our administrators many community groups Each time you create a group a category has to be assigned. Why can the drop-down to access groups in a profile not be separated by group category for ease of finding them? For instance, if I am an administrator, and I drop my groups down and want to find a Parent Group, then the category that says Parent Groups could be located and I could look at only parent groups instead of having to look through all the groups I have.
This is a suggestion that would help compensate for the unorganized mess your Community Groups make for a user. They are access based to set them up as smart lists and offer no efficiencies in the way of organized utilization.
