Ok i'm a estate manager for a friend of mine. On my parcel (1/4 of a sim) I have a large space which is public. I subdivided that space into a parcel i wish to make private. I set it to allow only group members in however even non group members can still walk in. I don't know if it is a whole estate issue, my parcel or what. But as i am trying to rent the private spot out i would like it to keep random visitors from dropping in unannounced. If there is any information i missed or any hat is needed ill be happy to provide thank you for assisting me.
