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?
if you remember your user name or password then you easily login in to your account other you need to your e-mail to forget.
He really needs to know email if he forgot password though. If you use secret question it locks account due to security, so
DO NOT use secret question to try to change password. So he either needs to find the email or hopefully he had account staked and can prove ownership via signing on the forum.
If he forgot user name, email, his posts, etc. Not going to be much you can do to help him.
