Another site has joined the wechall network and has been put into the rankings. Hack-Me is a very new challenge site from South Korea and currently offers around 50 challenges from the classic categories:
The site is available in Korean and English, and the challenges seem good, as reported from some players.
Because it is only a few months old, you might find tiny errors across the site, but i am sure you will enjoy the challs.
Thanks go out to cherishcat for creating the site and implementing the needed scripts.
