    Do ya come from a Land Down Under...
    Wondering if anyone here was a wiz with creating FB Apps?

    I need to create a simple FB app that enters the user into a competition to win an item.

    I'm reading about how to do this, but mainly... at least to start, I need to know how to get the user to click the Like button to start, as in the following example:

    That's for starters!

    Hope someone knows more than I do about this!

    Many thanks in advance

    When the client's browser iframe gets sent to your app, Facebook appends a signed request to the url (GET). You can decode this and find whether the parent Facebook page was liked or not.

    Search for signed requests within the Facebook Developer documentation and you'll get examples for a few different languages.
