I seem too have been allocated 3 nicknames. I got 2 emails, one with donator name of Xmas2015SantaB4438 and one with Xmas2015SantaA4438. Both address labels said the donator was Xmas2015SantaC4438. I can't change my name to Xmas2015SantaC4438 because it says the name is in use. Not sure what to do! Thanks.
