If I am correct, Badspot wont change the email to the key, cause my current key (Which I still have) is set to an old email address that I don't have anymore, I've emailed him, and PM'd him before, and never gotten a reply about it, so I'm assuming he just saw it and ignored it.
Edit, I saw your old topic, if you lost your key he will definitely just ignore it, or reply saying that he cant change/send you the key since he won't know for sure that you are the original key owner.
