The email on your account is a gmail starting with "j"? If that's still current I'm not entirely sure what's going on. Looking at the logs I see three emails sent to my admin account from the board that I never saw. Fortunately, I can change your password for you, and you can reset it to whatever you want. I'll send the new password to the email on the account.
Quoting from the text displayed between the "Summary" box and the "Save changes" button on every edit page on the wiki: "If you do not want your writing to be edited mercilessly and redistributed at will, then do not submit it here." So even if the new user is a sockpuppet, he has no grounds to complain if somebody else edits his contributions. And we do prefer that incorrect statements be edited.
