Pretty cool. Recommendations below:

1) Have the original authors post a description on their thought process when solving the puzzle

2) Have voters discuss why they believe one process is better than the other.

Both points 1 & 2 would help make CFC a learning material for new developers (such as myself)!

Thanks for the reply. Both of these points could be achieved my people using the fight-description box and voters could comment with their reasons for voting for one or other.

Nethertheless, maybe this could be made more obvious.

Thanks again!
