We have added more search capabilities for referral codes. Referral Tracking is a powerful tool to see which participants are getting more participants to join. It can also be used to incentivize partners like running stores or Cross Fit gyms attract runners.
We are now tracking registration ID and creation date to referral codes and added search fields for those. The registration ID is the primary registration ID when multiple people are registered at once. The past data was updated with best guess registration IDs and creation dates.
