Username has already been taken

I deleted my account by mistake and when I want to recreate it I have the following message :
“Username has already been taken”

I ask to send me a message to forget password but I do not receive any mail …

can you initialize my adress mail ?

When you delete an account, you are warned that the email address associated with that account is still being held for a month.

You can either wait a month or restore the old account.
Do you want to restore the old account?
