The Teen Grid existed as a segregated area from the original Second Life world (Main Grid, which was initially restricted to persons aged 18+), from February the 13th 2005 to January 20th 2011. Prior to the merger that saw both grids physically united as one, residents on Teen Grid were aged 13 to 17, and would be transferred to the Main Grid upon reaching their 18th Birthday. The rest of the former Teen Grid populous were given access to what was previously Main Grid (With the exception of "Adult" regions) and transferred alongside their assets.
