I'm new to the site, and yes I'm not in many RPs at the moment, but it does generally seem like a good community here and the Mahz is putting a fair bit of effort into developing the site. Sites will always fluctuate in numbers, it's just how they work. What makes a difference is the regulars and their commitments to helping newbies into their first, second and third Roleplay.
I also noticed very little aggression here. Maybe I'm missing it, but so many other forums I've been on (Anime, Graphics, Gaming, etc) have always had people that are either attention seeking to the point that it's sickening, or aggressive keyboard warriors that have no regards for other's feelings.
