I agree with pdb1 and Easy Edward communication inside the cc is key to keeping members at you're my cc's.
Let them know that these people are out there. Educate them on the color of the invite. This will let the members know what the invites intent are. Friend, game, join my club because it is better that the one you are in lol. This help a lot especially the new players who do not know the ropes. I hate to say this but when you get a TP in the club who wants to learn and is shown the way up the ladder he does not want to leave as long as you keep a good run club with lots to do in the cc.
If some of them leave they may not even know they are in another club or why. The communication piece is one of the most important parts of an owner or director of a cc Know your player and keep them happy and all the invites in the world will not pull them away.
May you make all your long putts and the wind be at you back
Have fun good luck hit em straight
