so to add somewon as a friend or foe, you need to click on their user name, you should be in their page now. then you click add as a friend or add as a foe. Foes do not see your posts, you dont see their posts, and neither of you see when either are online. When somebody adds you as a friend, or you add somewon, an invite will come to them or you. for example: if rose would add me as a friend, an invite would come asking if i want to let her be my friend. To see if you have any invites, go to profile, friends and foes (located right under profile) and see recieved invites. to accept an invite, press accept, to decline an invite, press decline!

have fun!
