Add Friends and Private Chats Between Friends
I think this is needed purely because sometimes we just want to say something to another user and we can't find them because they're in a different global and in another clan.
There should be some way to communicate with them.
You would be able to add them by clicking on their profile. Your friends list would be the same as your Game Center list. When you go to their profiles you have the option to set up a private chat with them. This takes up a third space in your chat thingy. You can only have one at a time.
