How to create a sandbox on my island?

[Jasperi]

So how can i create a sandbox on my island?

First i have subdivided a parcel on my land, using the buld -> land tool.

Where can i set the setting for that specific parcel that everybody can build?

Do i need scripts for the cleaning of that parcel?

Having a sandbox can be a mixed blessing.  I suggest having clearly posted rules for sandbox users and being prepared to spend some time dealing with the small number of people who will test them.  You can save a lot of cleanup headaches by setting an autoreturn for rezzed objects. You'll probably want to give thought to how to deal with weapons, vehicles, physical objects, particle emitters, temp rezzers, and very large structures --- none of which is "evil" but may still be a source of conflicts between users if you haven't spelled out guidelines. I also strongly suggest making terraforming impossible.  You do not need scripts for "cleaning" the parcel, but you might want to think about scripts that can keep track of who's using the area and can notify you when you need to come in world and pay attention to something.
