@Gila, CC levels work similar to personal levels - they rise with points collected by the members.
From level to level, new features are released to the CC and it's members. Most important is the member capacity which rises from 15 in L1 to 250 in L11. The most useful gadgets for the individual members are free Putter and Shot Pal in L2 and L4 respectively.
Are you looking for a CC?
More important than level is activity and cameraderie in a CC. This starts from the owner which has some exclusive and necessary powers.
Therefore, go to the profile page of an interesting CC and look up the owner in the members list. On the right hand side, you see when he played his last game. This should be recent!
By sorting the members by "Date last played" you see how many members are active and if they correspond to you in time zone and tier.
If you want to apply for the CC, my advice is to write on the owner's wall instead of sending an invite. Go on from the reaction.
To enter a CC as a member is cost-free and non-binding. Therefore, you may check out the CC and leave it if you want to.
