In the past. Speaking(2012/2013) on the Dutch forum we had quite a community of 45 man players who would often rail each other/discuss together hands-on skype. In general work together on their game. Unfortunately, those games are death(and Dutch forum too). I am now playing 18mans with the full ambition to crush the highest limits in it.
But would be fun to have a similar group like back in the day. Not necessary to big(3-4 can work very good). Not sure yet about the communication platform. Feel free for any feedback
