My FC on Ultros usually has about 15 to 20ish members active (been kinda weird lately with the expansion nearing and people finishing all the content so they aren't playing as much). We're pretty friendly and between that casual and hardcore raiding mentality, one of the reasons I'm with them ^_^'. Though our server community as a whole is kinda mixed as far as people goes. Mostly friendly people and there's the token not-so-friendly people you'll find on most servers.
