It has come to my attention there is a bug that when someone requests a friendship, the person they are requesting it from, their contact info shows even if they have it only available to friends, the area where you enter your skype, yahoo, AIM, email, etc. So if you do NOT want this showing, do NOT put it there. This bug will not be fixed anytime soon, so you've been notified. So if you truly are concerned about ones not on your friend's list seeing it, do not put it there in the first place.
