My boyfriend invited me into Google Latitude. There was just several times that my boyfriend asked me if I send him a ping so he will update his location. I don't remember doing it, and now I wonder if all of my "google latitude friends" are sent notification so that they will update their location WHENEVER I REFRESH MY ACCOUNT. I see that all of them update their location and get back to "zero" automatically without me sending them a "ping." Would anyone know what or where i can find the answer to this? Thanks!
