I have developed a flash game, which runs on a website and is not supposed to run directly on Facebook as iframe etc. I have registered an app with Facebook and have id and secret, have entered my app domain for auth and enabled highscore, but when following this tutorial:
<http://developers.facebook.com/blog/post/539/>
I do not receive the signed\_request. 

Is it possible at all to post scores to Facebook profiles from an external game, or does the game have to run in facebook as iframe?
