When any role in a group has the ability to "manipulate group objects", this also gives those with the role the ability to return group deeded objects, which is not described in the role ability. This has existed for a long time and is often exploited by disgruntled group members to trash other peoples property, and cause financial loss due to bugs in returning group deeded objects properly. This ability should be divided into two abilities: a) to operate the scripts and modify the prim parameters, position, etc of group deeded objects. b) to return or delete group deeded objects LL might also consider separating (a) into two abilities so that renters can operate group deeded scripts (like televisions, etc) but not modify the objects otherwise. ALSO: Objects owned by an individual but shared with the group can be returned by anybody in the group even if they have no abilities. This may be necessary for group building projects, but may also cause other issues. For instance, with rental groups, one renter in one parcel could return all the property of another renter in another parcel. This is a serious problem.
