One golfer can keep score for their group in PlayThru. When a golfer opens the event link, they'll be taken to the Golfer Select screen (see above). This screen shows all the event golfers.
The golfer can select up to four names to keep score for. This means the group can designate one person to keep score. That person can then open the event link and select the group's golfers. From there, they can tap "Tee Off" button and start entering scores.
The rest of the group can keep tabs on the leaderboard if they want. They can open the same scorecard link and scroll all the way to the bottom of the Golfer Select screen. They'll see a "Spectators Only" button, which they can tap and go right to the leaderboard.
