• Teen Second Life is an international gathering place for teens 13-17 to make friends and to play, learn and create.

In compliance with Linden Labs Terms of Service - we uphold the age restrictions placed on the main grid. Any avatar claiming to be or known to be underage will be reported to Linden Labs immediately and banned from all of the ALS estates.

It is a primary concern of ours to keep Second Life a safe and legal environment. Second Life Residents are held to a clearly defined Terms of Service and Community Standards to prevent illegal and/or broadly offensive activities, and it goes without saying that anyone engaged in these activities will be permanently banned from Second Life. Additionally, it is important to clarify that when we discover minors in Second Life, or when their presence is reported to us, we terminate their access. Underage users are automatically directed to Teen Second Life, an area specifically designed for non-adults, and offering them a rich, creative experience collaborating with other teens.
