I got proof of that today when i randomly logged in on an empty water sim and landed 1m from an old friend from Swedish SL :D
I dunno what she was doing, maybee sending some radio signals or something. She had a peculiar hat on. I dunno, i have to ask her when she wakes up :D :D
What I was doing in that location, in a pink dress and default avie? U can only guess….
