User Support & Resources - Merging new account with old account?

Hey, been about 6 years since I tried to login to the forums and I've forgotten my old password. I also don't use the email address that is linked to the account.

Made this one using the google login, wondering if I could merge? Or possibly delete the old one and make the username of this one wills0r instead of wills0r2.

Thanks in advance.
