Hi UK,
Right now Country Clubs are still in their infancy and are mainly just small groups of friends who know each other well or play together often. Country Clubs get their own private forum for communication too, so you can keep in touch with your fellow members.
Country Clubs will soon be able to host their own private tournaments. Later on we'll look to do official club vs club events as well as some other things that players can do within their club on a regular basis that I can't quite go into details for yet. There is much in store. =)
