Another question here, I was under the impression that you could only recieve messages in bottles from other people if you were both in Tag mode and passed each other. I had gotten some from fake people within the game, but the other day I got one from someone who said "Dear stranger, please add me: [friend code]." First I lolled, because this person obviously doesn't understand anything and is probably standing there with his gate open all day crying because no one visits him, but then it got me thinking =o
Maybe I just heard wrong and these things work online too, but could it be that I had indirectly connected with someone who HAD been in tag mode?
