Hello Dear Challengers,
We think its a good idea to announce join requests publicy.
The next site that will join might be http://thisislegal.com/
Its a new site with around 40 challenges by now.
In my opinion it looks attractive, and we did not spot bad challenges so far.
Their wechall scripts seem ready, and i guess they will join in the next 5 days.
Check the site out and share your impressions, if you like.
