When you book a tee time through the online tee time booker, you have the option to invite buddies to join your tee time. Once you have selected your desired tee time, you will see a section called "Invite Friends" on the tee time confirmation page. Here, you have the option to invite buddies from the Oki Golf Community, or email friends from outside the Oki Golf network to your tee time. Your buddies and/or friends will receive an invitation by email to your tee time, with an option to accept or decline the invitation. After you have booked a tee time, you can view your invitation responses and invite additional buddies from the "My Tee Times" section of your profile page.
