Common scenario at every course/club I've played:
You have a regular (daily, weekly) group that goes off in a block of 3-5 consecutive tee times. The group plays one or more games (bets) that span all these foursomes. After the round, someone spends 20 minutes figuring out who won what bets. My current group plays 5 different bets--low net front, low net back, low net total, net skins, and gross skins
I'd like to have each foursome keep score in GolfCard, then upload their scorecard to OobGolf. On your site, we would set up the different bets we're playing by selecting from a list of checkboxes. We would of course have to identify the golfers/scores to include. Your software would do the rest, and show winners for each bet and how much each golfer wins or loses.
I think this would be a good addition to your Groups functionality.
