Finding the e-mail currently registered to an account...

Sup, I have an old account that has an e-mail registered to it. Looking to sell it but I forgot what e-mail it was. Is there a way I can check?

Changing the e-mail and then checking all my e-mail addresses for the notification isn't an option since I have a ridiculous amount of e-mails and I registered it a long time ago.

 

No, I don't think there is another way. However, you can unregister an unknown email. Check out this guide: http://www.sythe.org/showthread.php?t=879810

 

Too bad that hasn't worked for a VERY long time..

 

when you send a request to change the email it will say it sent a request to both emails, and tell you what the registered one is.

even if you don't know the registered one, you can still change the email in 14 days.
