It used to be that when we attach a related page (similar game, friend, etc) it would be a two-way association. The page we were editing would also appear on the page we just added, and we'd be rewarded a point for the newly associated page too. Now neither happens.
I just added a friends to a character, and then I had to go add the friend from the other character page as well to make it work.
The points are also important, because that's where most of my Xfire, Steam, PC and Virtual Console points came from. It's where all my Pinball genre and Anime theme points came from. It also makes it easier to identify who might have made the connection, though this is kind of moot right now because the connection itself isn't being made.
