Hi all, Sorry to make such a beginners question (and sorry if the tech forum isn't the best place for it), but I have been looking through SL Wikis and not quite getting the answer. My question is simply this: When I first created my avatar I was dropped onto a beach. I did not select this location, it appears it was pre-selected, or it just happened (SL is running on my work computer where it has been installed by someone else). I assumed this meant that every new avatar was dropped into the same place on the beach. Is this correct, or are new avatars scattered around the world? The reason why I ask is that I would like to get a whole group of people on their own computers (not mine) to sign up at the same time, and I am hoping we will all be dropped into the same spot, so that we are together within the game in order to create a performance. Will this happen automatically, or do we have to type in a location to find each other? If so, where is this typed in - preferences? Similarly - If it is so that new avatars are dropped into different places, is there somewhere that gives me the coordinates of where I am so that others can type in those same coordinates and find me? I've seen pieces of code for global positioning, but as I am a beginner I'm not sure how to use it. Thanks and sorry again!! Cheers P
