I have full member account registered in late 2014 and now i forget my login email address,what i need to do to recover it?
There are a couple options:
1) if you don't have your email address, but still have the user/password, you can just login to your account and change the email to the correct one
2) try out every single emailaddress you ever used
3) ask Theymos to reset your password... Mind you: this request has to be made in a very specific way, using a signature from an old, staked address... And even then, it's up to Theymos wether or not he'll grant a password reset, and even then it might take a really long time
4) forget the account and continue working with this one.
