This isn't the place to ask, Programming Help is made for people to ask questions and submit things regarding programming. But no, you don't have to request friend adds or anything currently. They plan on putting something like that in AG3, similar to Facebook where you send friend requests and people accept them. And no, there's not a page with all the players or anything like that. You can go to certain users profile pages by typing armorgames.com/user/THEIR-NAME-HERE to go to their page and there will be a big "Add Friend" button on their profile.
