After exploring the capabilities of Facebook's fb:friend-selector, I successfully integrated a multi-friend selector into my IFRAME FB application.
Now, I am faced with the task of determining whether the user has selected any friends to invite, as I intend to reward them with additional points. According to the developer WIKI, the [ids] are passed to the requested page via POST. However, my question is how can I extract these values using JS/.NET? Ideally, I would prefer a .NET solution to easily store the values in a database.
