The TOS say that an app is not allowed to control the parent window, which is why there is rNT. A major use case for wanting to do this however is linking new users to your app's install page when they're viewing a friends profile. I asked about this a couple months ago and was told that you would have to use target="_new" and pop up a new window. However, I'm seeing a ton of apps that link to their install page in the same window using target="_top". Is this allowed now?
Thanks
