How to close PN account

Hello,

Though I was a happy user of PN for a while, I haven't been using my account for years. There's nothing wrong, I'm simply elsewhere.

I have removed all my pictures. I would now like to close my account completely. I've searched to find out how to do this, it seems to be a mystery to many people.

Could someone please tell how to close my account? I could simply change my contact email address and never come back, but I find there should be a way to officially leave without seeking out and leaving a fake identity behind...

Thank you
