Here we have our first weekly challenge!
It consists of a weekly activity. I will propose you a challenge on Tuesdays... you will have time to participate in it through the comments in this blog until next Sunday night... and on Mondays we will have the solution and the winners of the week.
The 3 winners (the 3 faster, the 3 more original, or the best 3... it depends on the kind of challenge) will have a positive!
So... this is the first challenge!
What is it?
Where can you find it?
