My friend would like to join Warmane again but he's forgotten his username and the 'forgotten username' system never seems to send an email to him, he also unable to create an account as it says his email-address is already in use.
Why doesn't he make a new e-mail?
If he wants the old account really badly he can send an e-mail to [email protected] with all proof he has to prove ownership of the account and hope they can help him. Reply might take about a week.
