Hi gene,
If a player requests an invite to your club you'll receive an email notification. That email will contain a link you will need to click to confirm that you do want that player in your club.
After you confirm another email goes to the player so they can accept
the invite and join the club.
If you're recruiting yourself you can visit any player's profile and
click the "Invite to Country Club" button that shows up above their name
and scoring average. That will send an email directly to that player
(assuming they have the correct email listed on their account page) and they will have to go
to their email and click the link within to confirm they wish to join your club. I recommend dropping a note on
any player's wall that you send a club invite so they know to look for the invitation in
their email. If they're not receiving their invites via email be sure
to tell them to double check that the email listed in their account settings is
correct and to also check their spam or junk folders.
