Welcome and glad you enjoy this easily addictive game. You're a new player and brave one at that...opening a Country Club (CC) as an amateur is an aggressive move. Cheers and best of luck to you in this endeavor. As to how to manage tournaments and things as an owner I've included a pic of a CC's Main Page...You get to this page by clicking on the CC name from your profile page...
1) You create tournaments from the areas I marked #1 in the pic above. From this area you choose the courses, what tiers can play, choose tees and green speeds, etc. You'll become an expert in setting up tourneys in no time. Very easy.
2) The CC Forum you access via either area marked #2 in the pic above. You'll know what to do w=once you're in there.
3) Then as an Owner of a CC you have Owner's/Club Tools marked #3 in the pic above. From that area you can invite people to join your CC, delete members, etc. You can also make members Directors...they'll have less power than you and you grant them when you want to allow them to do.
The site is very basic and I'm sure you'll figure it all out from here.
Again...Best of Luck!
P.S. If they are fatigues in your profile pic...and you served...thank you for your service!
