Are there any rules that govern use from not just giving the answer?

anonymous · Answer

yes it is in the code of conduct

anonymous · Answer

Do they enforce it?

anonymous · Answer

yes

anonymous · Answer

Since there is a large diversity here, I think it would be hard to enforce.

anonymous · Answer

I am glad they have changed their policy. They used to not care if you gave the answer. Under a different account that I had long time ago, I actually spoke out against open study members just giving the answer and said this site will be labeled as a cheat site if it continued on its current course.
