I discovered WTM just one month ago, but I'm already hooked: it's a great and highly addictive site! :)
The challenge to be the first to solve any new submission is pure thrill...
I am slowly understanding how everything works, I'm also uploading my first screenshots, hoping to get some of them in the FF section.
With a lot of work and research I am now 7th in the FF score: to go higher is apparently impossible: congratulations to everybody in the top ten, especially the ones in the first five positions! :)
