If your event was automatically imported from the AMA calendar and you received a notice via email, once you register on RCPilot (with the same email that was used in the event), that event (or multiples if you have them) will automatically display under your "My Events" area! You can click the three-dot menu on the event listing (click to expand the event listing and you'll see the 3-dot menu on the upper right) and you can edit the details!
