I did send a pm and there was no email. If I changed the email, I assume PMC would send me a notification email telling me my email had been changed, right? Also I've used every single email address I've ever used to login and none worked.
Thanks for these suggestions but I am already sure about what email I used since I found some old emails from that PMC account on that email. And I never linked any social media accounts so that's not possible for me unfortunately :(
