Other things to keep in mind:
The name you use should be your real name as it would be listed on your credit card, driver's license or student ID
Nicknames can be used as a first or middle name if they're a variation of your real first or last name (like Bob instead of Robert)
You can also list another name on your account (ex: maiden name, nickname or professional name) by adding an alternate name to your profile
Profiles are for individual use only
Pretending to be anything or anyone isn't allowed
