It was my impression that there wasn't one, so I've made a Steam group called "Watch the Guild" for all who's interested to join.
Here's a link: http://steamcommunity.com/groups/WatchtheGuild
Personally, I'm mostly interested in playing Magicka in the moment. I'm pretty crap at FPS games in general :p
Oh btw, would it be ok for me to use the default watchtheguild avatar as the avatar for the group?
