We need to ensure that you actually own the character that is going to participate in the Iron Teams challenge. We create a user based on your BNet tag and BNet name (not your real name). For example, my recorded information is BNet:Leeta#xxxx & Name:Leeta. We do NOT show your Battle Tag to anyone except yourself. We also do not have access to your email address or real name. We do NOT have access to modify your account or characters. Battle.net information is limited to READ-ONLY (meaning we can’t change anything): Battle.Tag, Battle.ID, Character Information.
Managing Iron Teams data is much easier by using your registered Blizzard account.
