Could we get an explanation field for challenges?

Question

When I do challenges I like to look at the correct answers to learn from my mistakes. Often I get it when I look at the solution but sometimes I would need an explanation. It would be cool if an optional explanation field could be added on the code factory.

Answer 1

I was looking for this. Just posted a quiz/challenge question. I see the answer. I don't understand how it was derived.

Answer 2

I've so many challenge questions I don't understand! It would be awesome if sololearn included the explanations. It would help in learning.
