what has worked for me is adding the friend ID but usually it requires taking a photo or writing it down then type it on friends app.. but still there's no way to chat or socialize other than through these kind of posts..

even after posting this reply you will have no way of knowing I just replied to you, you have to manually check on your profile's activity lol I'll leave my friend ID, do add me

5126-9754-8739, write it down then add me :) so far the only game I know has a chat function is monster hunter 4 ultimate, if you want to let me know anything reply to my latest post on my profile
