I just installed a new challenge from Jinx
It seems to be a quite unique idea, and nicely fits into the wechall challenges.
The categories are Stegano and Encoding and it's worth 3 points.
Thanks to Overclok and paipai the challenge description is also available in french and spanish.
We all wish you ...
