As is, "Allow Push" only has a check mark in the about land info, there isnt even an option to grant this power to just group members.
I propose that the this ability be added in Parcel Powers, in the Group menu.
This will provide utility (and more importantly an element of fun).
To controlling ne'er do wells.
Example, if a parcel is group owned and the group has a Police Department to maintain order, those in the police role will have the ability to restrain said person and pull them aside.
Theres also other places where this ability will prove useful.
