I'm fine with that, but since some content is taken directly from unity forum/answers posts, are there any problems with that?

That's a good point, and a tricky one.

From my understanding, having no license is against the point of having a library like this. Indeed snippets from forums usually do not have a explicit license but the fact that somebody made it public in a forum suggests it should be used by others with access to the site. I see this as an implicit permission for other people to use and makes licensing the code a logical step.

When looking at the main [http://choosealicense.com/licenses/](licenses suggested by github), most of them also list "patent use" as part of the permissions and that would probably overstepping boundaries of code posted on forums, despite being unlikely. The ones that do not are the MIT and The Unlicense, the latter being the one I would expect some poster to dislike as being too liberal.

When I suggested the license I was following the concept of "any open source project should have a license" but that actually that depends on whether this repository is comparable to a "standard project". If the decision would be not having a license, I would suggest just making it clear in the README and maybe having a policy of having a comment with a link to the forum post or something similar.

The terms of Stack Exchange have recently been changed to make all code posted on their websites available under the MIT license. It would also accept a "link to the post" option I mentioned but there's some controversy on the maintainability of that approach. I see the full MIT license in this project as a having the potential to simplify the proper attribution (albeit indirect) attribution.

Hope I helped and not raised too many new questions 😄
Maybe you should get some input from more people before making a decision.

there is one comment in the forums about licenses,
http://forum.unity3d.com/threads/the-unify-wiki-are-you-aware-of-it.179901/page-2#post-2795114
(and unity wiki was supposed to switch on public domain also)

So i think we'll go ahead with mit now, and adjust if necessary. (i'll merge on weekend, if nothing else comes up)
