Sometimes when I play I will see others with names like simply Aaron and not the usual name like Sally StarFire. Why is this? Is it like something you can earn or something? Thank you for your help!
When you creating a Wizard, only the first name is required - the two-part last names are option, and the name selection wheel offers the option of <none> in both those locations.
Click the "New" button on the Wizard selection screen when you first start Wizard101, and check it out! (don't worry, you can have up to 6 Wizards, and making a new one will not delete your existing ones)
