When people are setting up their profiles, they can type anything they want into the place where you enter where you're from. You could put "Oz" or "Third Planet From the Sun" on your profile, and when you visit people, that's where it would look like you're from.
Thanks Cheryl, to be honest, I didn't know how it picked up the location. When I look at my own photos, the location that comes up from my own view of the image, is one that I have never actually typed in. It's not even a part of my address.
I've had visits from A2 before, and normally I'll check weird IP addresses just to see where it's located. In the case of A2 I didn't do that.....but I will next time. :)
