How to name change

I can not find the official instructions and parameters for changing name on Battlenet for D2. Can someone please link?

  • Log on to the character you wish to rename.
  • Enter a chat channel.
  • Type the command: /rename-character confirm
    (if you don’t add confirm it will keep asking you if you’re sure).
  • Check your registered e-mail for the character rename link.
  • Stay logged out of your character for 10 minutes for the link to work.

Thank you. How long before the old name is available again?

Hmm when i do that it just says that the command is invalid…
