If bạn want to change the biểu tượng bạn need to speak to this person link who I believe is the spot creater, she is the one with the ability to change the icon.
Oh yeah we really need a new icon. We could use a new banner as well. It would be cool to make a contest and make banners and have people to vote for the best one, what do bạn think? But the girl who made this spot would have to agree since she is the one who can change them.
