I forgot my original password and email

My Forumotion has been created for many years, but I have forgotten my original account, so I can no longer manage it. I don't know what I should do, I came here according to the help information in Forumotion, he needs me to publish a post to send a private message to the administrator, I hope what I do now is useful, thank you.
