Joined almost three weeks ago myself and am very happy with the group. People play in a variety of time zones so there are people around at a lot of times of the day. I really like the team-focused attitude and that inactive/non-communicative players are regularly removed.
Don't be afraid to toss your name in the ring even if you're newer. I joined at level 26 and I'm level 109 now and was first able to hit the 100,000 gold contribution this week, but I was able to hit max seals and 150-200+ trophies weekly since joining. Like Danko said - if you're active, you might find a home with the 404 crew.
