[amsat-bb] Changing callsigns for AO-73 Dashboard

What's the correct procedure for getting my callsign updated on the FUNcube Data warehouse? I can't seem to just register a new account as it says the email address is already in use. I did find this question on the forum, but there was no answer:

I've also uploaded data for Nayif-1 in the past, but I can't remember if it uses the same account.

Thanks! 73, Loren K7IW formerly AG7NC
