I created a new challenge for MapRoulette: "Fix waterway direction".

however, due to data errors, not every time. That's why I created this
A more detailed description can also be found on my user diary here:
I started with the really easy ones and only Europe for now. I will
upload further tasks soon, worldwide coverage will follow, too.
Hope you enjoy this challenge,
