Maybe there's already a way to add a guardian to your friends list from this site, but if there isn't there should be. I'm on here quite a bit when I'm away from my PS4, and I'm meeting some really cool players, so it'd be nice to add them as friends/send friend requests with a couple clicks. I've also read posts from players that seem to feel alone in the Destiny world and it'd be nice to give them access to my list of friends, too.
