@Rich: I created this thread so TGC forum users could discuss the issues they're having here instead of derailing other threads. Also, I don't see FE and AppGameKit as mutually exclusive products. However, I do agree that most of the issues raised in TGC threads should be raised in the FE forums. This thread is here for those who haven't migrated to the FE forums yet.
@The Daddy: TGC would need to answer that question but they have upped the level of security of your compiled apps. You need to officially click the deploy button for your app to be made public. Previously you could access anyone's project by playing with the play ids.
