Friend Options
This is where you have checkboxes if you want to make your location public (Makes your friends warp to you) or not (Private).The "Show Friend Notification" check box means that if you check it, You will see your friend/s going on and off (Ex. <name of friend> has logged off.) It could also indicate how many friends are online when you log on.
