Any CP members use
TribeSports?
Generally, I'm not a big fan of social networks and have basically entirely given up things like facebook, but this is a social network based entirely around sports, competition and health. You participate by joining sports or interest based groups and setting/completing challenges. As you are more active your ranking moves up in the community.
It's based in the UK, so most members seem to be there as it also seems quite new, but I really like it and thought it would be cool if other CP members were on it and interested in taking challenges.
