I have already created a Game app in Facebook, and have posted achievements. So far so good...
The problem is that I now want to add a tab or block within users' profiles, similar to how Foursquare does it (see attached image), but can't find documentation about it.
Does anyone know how should I do it?
Note: I think I'm using FB's latest UI
UPDATE: I've added Codecademy as another example
