So, here it is. pK's own facebook page.
Just remember that the forum is still the main communication about in-game stuff. This page is secundary and only in order to get to know each other better. Or for instance call for a quick 5th member in pvp or so.
No obligation to join, feel free to join out of own initiative. You miss nothing since the forum is still the place where everything is published.
(this is a work in process btw)
