" a Permanent Education Space for yourself in Second Life

If you would like a place of permanence on the Second Life Grid, Private Island ownership lets you create a secure "intranet" space with restricted membership for your students and faculty, or you can open it up to be accessible to everyone on the Second Life Grid. We offer a discount for Private Islands to educational institutions and non-profit organizations. You can find details on the Private Island order page. You can also optionally buy a plot of land on the mainland of the Second Life Grid if you want something smaller and permanent (we don't offer any educational/non-profit discount for such plots)." from Second Life Web Site
