There is already a potentially disastrous issue developing on OpenlifeGrid, and it's not technical.
At the moment, there are two underage users on the grid and in the chatroom. One is 15, the other says he is 11. (Of course, it is possible that one or both are lying, but many of us have had extended conversations with the 11 year old, and several of us, including me, believe that he's the real deal. Either that, or he's an incredibly good roleplayer.)
Discussion has turned to how to create an appropriate policy for this. A number of people (myself included) have impressed upon Sakai the need to deal with the issue, PRONTO. I can forsee a time when OpenlifeGrid is overrun with children and teenagers, because there is no age policy in place.
I'm in favour of an 18+ only age restriction, perhaps with a separate grid for kids and teens as
SL does. Either that, or a PG13 grid with all adult content banned.
