First off, I've added the beginnings of a friend system. You can get your friend code on the account page, share it with others, and add other people's friend codes in order to establish a network of friends. Right now being friends doesn't do much, but soon there'll be some nice features such as zeny and chip transfer between friends.
Second, I've updated the help page. It now provides some information about what the deck, folder, and sack are for people unfamiliar with how things work.
