I have an app that allows users to generate and publish content. I would like to possibly be able to use the content they publish/create to make derivative works, ie books etc (similar to what icanhazcheeseburger has done.) If I were to put an opt in alert to ask the user whether or not they would like to be a part of this, would this violate the iphone sdk?

I know this is not programming question so I'm not sure if this is a fair question, but I thought I heard something like you can't add a eula you have to abide by whatever apple dictates in their app store agreement.

Also if you have suggestions on different ways to approach getting users to agree to this I'm all ears, but yes that is kind of subjective.

Thanks folks,

Nick
