Duplicate Bidders (with 2 different email addresses)
Double registration occurs when an auction manager registers a guest with one email, but the guest registers themselves with another. In many cases, the auction manager has a work email and the user signs up using a personal email address.
So what you end up with, is two John Smiths registered, with two different Paddle Numbers. However, your check-in team will look them up and not know which one to check into the auction. (hint: you always want to check-in the account that the user created on their phone for simplicity).
Instead of pre-registering guests and pre-assigning paddle numbers, our recommended approach is slightly different: allow your guests to pre-register themselves.
