Or new I guess. I presume this is a slightly older crowd though.
I worked on Club Penguin for 6 years after high school. Community support, game testing, file management and project management. It was quite a ride, and I sometimes wonder where some of the old fans are now. It's been plenty of time for some of those youngsters to be in their 20s (I knew one guy that was 20 when he was a super-fan... that was special.)
