What’s the copyright status of user-submitted content on Unity Answers?

If I remember correctly – and I might not – there used to be a notice somewhere on the site that every submission was under Creative Commons licensing (possibly cc-by-sa, to be more specific). Some sort of copyleft license is pretty standard for this sort of community-driven Q&A site.

I tried emailing Unity Tech about this, but never got a response.

At present, the best reference I can find is the terms of use posted for unity3d.com (which I can’t find linked anywhere on UA itself). That page does mention UA, the forums, and so on, and includes more limited terms:

By making available any User Content through the Site and Services, you hereby grant to Unity a worldwide, irrevocable, perpetual, non-exclusive, transferable, royalty-free license, with the right to sublicense, to use, copy, adapt, modify, distribute, license, sell, transfer, publicly display, publicly perform, transmit, stream, broadcast, access, view, and otherwise exploit such User Content only on, through or by means of the Site and the Services.

So, is any sort of copyleft license in effect, here?

In all my experience, no. No one can copyright ideas that they willing gave for the benefit of others. Plus any information we have is technically property of Unity Technologies since it is their intellectual property we are discussing.

Short answer: No, you’re fine man.
