Should I enter my score into the scorecard set-up for the original match when playing a make-up?

No.  Doing so could change your handicap and impact all matches played subsequently.  Contact us with the original date of your match, the make-up date and course.  The League Officers will set-up a new card for the date of your match.  Players should always use their current handicap (i.e. on the date of the match) and never a historical one.
