In case you didn't see my response on GameFAQs...

Everything looks great, though there's really no effective method of
knowing who's added who to each other's friends list... Perhaps what
should be done is that everyone who joins makes their OWN table on the
database, and everyone that wishes to add that person posts THEIR info
in that database table. That way that member can constantly check
their section in the database and instantly know who's added them so
that they can do the same.

I realize that may have sounded a bit confusing... Let me elaborate...

Let's say I start a database table called "Pink Kitty's ACWW Info",
and monsteratomic wishes to add me to his friends list in the game.
He'd submit his information to "Pink Kitty's ACWW Info", which would
easily tell me that I've been added. From there, I can copy his info
into my own friends list.

I really think this method would be more effective. As it stands right
now, no one knows who's been added to whoever's list. Please take it
into consideration. =3
