Linden Lab Official:How do I allow someone to buy a Private Region in a space that is next to mine?

If you own an Estate in the Second Life® world, you can allow others to buy land in spaces that are directly next to the land you own. You can specify Residents in the Allowed Neighbors list for each Region in your Estates. For example: Joe Resident and Helen Resident are friends who own their own Estates and want to be able to buy land in the Land Portal next to each other. Joe's Estate, Joegalaxy, contains a Private Region called Joetopolis. In the Land Portal's Estate Management tab, Joe can specify that Helen is an allowed neighbor for Joetopolis. Helen can now use the Land Portal to buy Private Regions that are next to Joetopolis, including spaces that only share a corner with Joetopolis. To specify a Resident you want to be able to buy land next to yours:

1. Log into the Land Portal.
2. Click the Estate Management tab.
3. Click on the Estate Name of the Estate for which you want to specify allowed neighbors.
4. In the Allowed Neighbors column, click the edit link for a specific Region.
5. Type the name of the Resident you want to allow as a neighbor into the text field and click add.
6. Click close. The Resident you specified can now buy land next to that Region.

To remove a Resident from the Allowed Neighbors list for a Region:

1. Log into the Land Portal.
2. Click the Estate Management tab.
3. Click on the Estate Name of the Estate for which you want to specify allowed neighbors.
4. In the Allowed Neighbors column, click the edit link for a specific Region.
5. Click the X next to the name of the Resident you want to remove.
6. Click close. The Resident you specified can no longer buy land next to that Region.

Things to keep in mind about allowed neighbors

Adding and removing other Residents to your Allowed Neighbors list can result in some interesting circumstances. Let's start with the following conditions:

• Joe Resident adds Helen Resident to the Allowed Neighbors list for his Private Region Joetopolis.
• Helen Resident buys a Private Region next to Joetopolis and names it Helen City.

Now, suppose ...

• ... Joe wants to buy a Private Region next to Joetopolis that also shares a corner or side with Helen City.
• ** Joe can't actually do this unless Helen adds Joe to the Allowed Neighbors list for Helen City.
• ... Joe removes Helen from the Allowed Neighbors list for Joetopolis.
• ** Now neither Joe nor Helen can buy a Private Region that shares a corner or side with Joetopolis or Helen City.
• ... Joe removes Helen from the Allowed Neighbors list for Joetopolis, and Helen adds Joe to the Allowed Neighbors list for Helen City.
• ** Now only Joe can buy a Private Region that shares a corner or side with Helen City.
