The biggest improvement to parcel control is the ability to use the Account Type information to determine which Residents can access your parcel. This setting is located in the "Access" tab under "About Land". Land owners can choose to allow access only to accounts containing "Payment Info on File" (this means that the Resident has billing information in their profile but has not yet used it to purchase anything) or "Payment Info Used" (this means that the Resident has used the billing information in their account successfully) in their profiles. The default setting of "None" means that no restrictions are in place based upon Account Type.
Torley,
This improvement is practically worthless. Why?
For one, it's not in the Estate Tools.
And two, the ban lines for this only reach 50 meters high... leaving skyboxes and higher builds and stores wide open to any and all, same as before.
Perhaps in the next update this could be added to Estate Tools?
