ScenarioFacebook app which resides on User A's profile (in a tab called Welcome). User A can fill out a Welcome message and update the message.User B comes to User A's profile, clicks on the Welcome tab and views the Welcome message written by User A.I understand how to complete the majority of my application and imaging that I will produce the response based on a DB lookup of a field associated with User A's Facebook ID.What I don't understand is how to grab the User ID value of the user who installed that instance of the APP (User A) or how to grab the User ID of the profile that User B is currently on (Which also happens to be User A).Any ideas on how best to attack this?
