If you have posted scorecards but still see no players on the ringer report (for example), it is probably because you have not selected the correct course. 
To correct the problem:

1. Go to 'Reports'
2. Select your report (the 'Ringer Report' in our example).
3. The next form lets you customize the report and select which players will be included on the report.
4. Click the button [Select Players to include]
5. The "Report Filter" form will appear.
6. Make sure the course for the option "Course Played Include ONLY players that played the below course" is set correctly.
