thanks for your swift replies! I am quit a long time on SL, but I find this subject difficult.
I think it would be best to set the parcels to invisible and not let the people on it decide, right? It takes away the flexibility but its safer, as people will forget, or dont want to set that setting.
One more question: if I set it to invisible and we all can assume its private then; can I as a landlord rezz adult furniture in the private parcels (set to group access if possible)? Or do I leave that to the people on the parcel meaning its their responsibility?
