Golf League Tracker has a number of ways to handle absent players for your league. Depending on your league type, you have different options detailed below.
If a player is absent on an Individual Player League, when entering scores you have two options:
If a Single Player Absent...
If a single player is absent on a 2-Player Team, when entering scores you have three options:
If Both Players Absent...
If both players are absent on a 2-Player Team, you can:
It's possible to have a sub play for one of the absent players, and the course play for the other absent player. It's also possible to have the sub play for both absent players. It all depends on what your league rules state on how to handle this situation.
See this example for more details on how scoring works for the course.
If a team forfeits, how you handle that is up to you. Most treat the team who forfeitted as you would any other team who was absent as described above. If you have special rules specifically for forfeits, when you "Record Points" you can override the points the system calculates and enter whatever you like to match your league rules.
Some leagues decide to have a random player play for absent players. To do this in Golf League Tracker, create a sub which will be your placeholder for the random player. Then, choose your random player using whatever method you use for your league. When you enter scores, enter the score for the absent player using the sub you created, and click the "Edit Handicap" button so that you can manually set the handicap for the sub.
I don't recommend using random players because it's best if players know what their opponents are shooting.
Some leagues have an odd number of players or teams, which requires them to have a "ghost". A Ghost player or team is treated just like a real player or team who is absent for that round, and you will follow the same procedure when entering scores.
In individual player leagues, most leagues give the player 2 extra strokes over their handicap (2 penalty strokes to the course).
In team leagues, most leagues have the solo player play both opponents and only use the course when two players on a team are absent.
