Today astalavista.com joined the wechall network.
They currently offer around 80 challenges from the usual challenge categories and also "shell challenges" on 4 wargaming boxes
Beside that, they have a huge amount of users, a big download section, tutorials and links that should cover our beloved hobby very well.
While browsing i also spotted videos, podcasts and much more stuff to explore.
Many thanks to sykadul and Phreak for implementing the needed scripts.
As always, we wish you all Happy Challenging!
