How do i add friends i've looked and really can't find a button anywhere.
One way is if you can find them on the leader board. I think you can also add friend through the chat thing if your friend posts on there or you can add random people I think on chat. But they don't have a good system yet. Just find people on the leader board and add them by clicking their name. They probably will come up with a good way for this soon in future updates.
