Right-Answer has joined the wechall network.
It is a brand-new site which offers currently 61 challenges from the following categories:
Math, Logic, Programming, Crypto, Hacking, Stegano.
The site is only one or two months old, with a fresh minimalistic design and is available in French.
According to the admin, Zathuros, the current problems should turn out to be quite easy, and he is searching people who would like to contribute stegano or hacking challenges.
Many thanks from my side for joining us!
The feeback on the site was not bad, so it is maybe worth to check out, and may it be for some french lessons only
Last but not least, we wish you
