Hello, i want to add my friends but how do i do that? I put there familyname in friendsearch but that doesnt work. And filling the large familyusernumber i cannot do, becouse ipad doesnt alow large title or numbers. Anyone? 

did you go to Social > Add Friend? did you search for your friend's name there?

edit: if it your friend's name is still User0834789347389 or something like that you can add him after the maintenance update since thats when the family names will be updated
