Second Life 8/29

Ok. I've spent the last hour or two on Second Life.  Mostly just "dressing up" my avatar (I feel like my little girl changing clothes on Polly Pocket or some other doll).  I'm not sure at this point I understand the purpose and function of this game other than meeting people.  Not quite comfortable with some of the language and name calling I observed from other avatars. I guess I need to understand the mission/goal.  Keeping my mind open....
