I have used your site to schedule a bridge teams round robin. A bridge team is formed with 4 players playing together in 2 partnerships. Partnership 1 sits North and South at table 1, and partnership 2 sits East and West at table 2, the opposing team of the day fills the spaces. I found using your RR generator easy to use and it has certainly eased the strain I was under to complete the schedule ontime.
Great site and I will be revisiting to look at the algorithms when I have more time.
