I tried to rename a char, and just before sending the request with the new name I erased the charname that I want to change, but it says "a character with the name xxxxxxx already exist".
Why? The name must stay erased for some minutes?

Sorry double topic, not understand how it was possible, just close one, please.

You have to wait 7 days after you delete a character before you can use it again in the rename function.

7 days? It is like "delete your name and you'll not found it anymore..."
