I am trying to create a new user with a new email address but get the error "Sorry, it looks like that email address is already in use. Use another one."
The email address has been created previously by mistake & then deleted.
I am sure that the email address hasn't been assign to another user, they are only 2 & I have checked the aliases.
How if by any chance the email address I need to create in the system can be removed entirely to make sure I can create a fresh one.
