Hi Callum, excellent charts. I am a subscriber since a year and got a message from substack (you?) that my creditcard was denied. I have sent an email, as it should work now. But the email-adress of substack was a "no reply". Could you pls let me know, which email address I could use to inform about my creditcard? I would like to continue my subscription. Many thanks.
