BigT612: what benefits are there for being part of a CC. Which CC do I “want” to belong to?
One benefit is company, so you'd be looking for an active club. Most important: An active owner. Too many owners don't care for the game and for their CC.
Check him for his "last game" in the CC list, then sort this list for "last game" and look how active the members are.
Try to talk to the owner, let him invite you - shows his interest in his own CC.
Another, credit-saving, benefit is free Putter Pal + free Shot Pal. Any CC from Level 4 has them.
Other than that, check the CC community after joining. Some have quite strict rules stating what they expect from you. Some socialize, some play matches, some gamble, some play the Clash Events. Some have special interests like sports or veterans, some prefer a certain language, some are international - all facets are available.
There's no costs attached and no obligation to stay - you can leave any time. Just be polite and say good bye.
