Username rules

  • 3 to 20 characters.
  • Letters and numbers only. Spaces are removed and the name is stored in lower case.
  • Each username is unique. If yours is taken, try a variation.

Display name

The display name is what others see first on your profile and uploads. Accounts of younger users do not have a public display name for safety reasons.
