[coreboot] How to delete another me?

[Zheng Bao]

Hi, admin of gerrit,

I tried to add my working mail address [e-mail] to my gerrit account. But it says it is used by another account.

I am pretty sure that is because I tried to use this mail address to create an account, but can not login by authorization.

I have forgot the account name and other information.

Is there any way to find out that account and delete it? Thanks.

Zheng
