Is there still closed private region for teens only?

[earthzero]

We want to set up an island for school teenagers, however the Teens Second Life was close. Is it possible to run a closed private island for students only in the main grid?

Hi earthzero,

You can always run a closed island.

Access to Second Life depending on age:

13,14,15 - closed islands 

16, 17 -access to General regions only, so you need to have island marked as General and you can close the access, but students will be able to teleport outside to other General regions.

Here is the announcement about teens in Second Life.
