I have a account with WSPR for my old callsign CN8QE
How can I delete this and make a complete new account for PA2KL

I try to changing the callsign from CN8QE with PA2KL but works that way.
I like to use the same email address

Is there someone in this for who know how changing my callsign ?
Or delete the complete acccount included with all my details.
