castleland is a Castle "land comm" or challenge community. Basically you join one of three teams (Detective, Writer or Medical Examiner) and then you participate in different challenges to earn points for your team. I'm a member of Team Detective (as if I'd be a member of any team OTHER than Beckett's) so I urge you to try to join that team if you can! You put your team preferences in order and the mods will try to give you your first preference. When you join, please put me (thecowboycliche of Team Detective) as your referrer. Thanks!
